Top 5 Nutrients for Growing a More Sustainable Cannabis Crop

When it comes to growing cannabis, the type of nutrients we use play a major factor in determining the level of sustainability that is reached. There are so many elements on earth, from land or sea, that can be used to grow a cannabis plant from seed to harvest. This can be obtained in many ways but the moist sustainable way, is using amendments that are made up of earthly compounds and introduced through the soil. There are many elements and nutrients that are vital to the growth of a cannabis plant but below you will find the 5 nutrients that are an absolute necessity for growing a sustainable crop and the organic elements that are used to introduce this to the plant.

Nitrogen is by far one of the most essential nutrients of the cannabis plant. It is so crucial because it is an integral part of chlorophyl and is key in the process of photosynthesis. Plant tissue is also made up of mostly nitrogen, which is why you will quickly see signs of deficiency when there is an absence of it. For a plant to feed itself and grow, there must be a readily available source of nitrogen within the soil or grow medium. Some of the most popular organic elements that are used for nitrogen supplementation include alfalfa meal, blood and bone meal, cottonseed meal, chicken manure, feather meal, fish meal, bat guano, worm castings, and many other natural resources.


Phosphorus is vital to the growth of a plant and is found in every living plant cell. It acts as a stimulant to support important biological response required for new cannabis growth, such as photosynthesis, metabolism, and nutrient uptake. The cannabis plant depends on the availability of phosphorus during all phases of development. Phosphorus is also one of the most limiting nutrients available globally. Large deposits of rock phosphate that are mined for commercial agriculture are limited to just a few countries making the demand high and the supply slowly decreasing. The most widely used organic amendments are bone meal, soft rock phosphate, high phos bat guano, fish bone meal, seabird guano, and shrimp and crab meal.


Potassium, the 3rd macronutrient, next to Nitrogen and Phosphorus, is another important catalyst in the cannabis plant. Although the presence of potassium is very limited in the plant tissue, it interacts with nitrogen and participates in the compound of proteins and amino acids. During periods of drought, it improves the resistance of plants and is the main component to the strength of plant tissues. Potassium also works in conjunction with phosphorus to improve the strength and resistance of the root structure. It also plays a major role in the increase of mass, density, and volume of the buds. The most used potassium organic material include compost, kelp meal, greensand, sulfate of potash, and wood ashes.


Calcium is one of the vital properties to the healthy growth of a cannabis plant and is one of the essential secondary macronutrients of plants. Calcium is needed in all phases of growth and is served in multiple functions. It improves the shifting of nutrients and is crucial in allowing the plant to absorb other nutrients. This is the main reason a calcium deficiency leads to other nutrient deficiencies. Calcium strengthens the cell walls in all areas of the plant and benefits the overall health of the plant. With improving the strength of the plant tissue, this allows for better resistance against diseases, pests, and protects your plant from heat stress. Natural sources of calcium include eggshells, lime, and gypsum.


Magnesium is one of the most important secondary macronutrients because it is an element that your plant needs in all stages of life in fairly large quantities. This element is most presently in the leaves and has an immediate impact on the plants ability of light absorption and creating sugars and carbohydrates. Magnesium also plays a crucial part in transforming light into energy. Some important organic resources of magnesium include dolomite lime and Epsom salts.

In conclusion, the top 5 nutrients for growing a more sustainable crop are the macro nutrients (nitrogen, phosphorus, potassium) and the “secondary” macro nutrients (calcium, magnesium). And the sustainability of the crop is strictly determined by the sustainable materials that are used to deliver these nutrients.

When early Americans started cultivating the fertile landscape of the eastern United States, laws were implemented requiring many farmers to grow and harvest hemp, a strain of the cannabis plant. One reason for this was to obtain the plant fibers commonly used to make paper, clothing, rope and other textiles at the time.

Perhaps a more noteworthy reason for the cultivation of hemp was for the tremendous nutritional contents of the seed. Hemp was considered “a necessity to the wealth and protection of the country.” Of course, today, the growth and cultivation of anything related to marijuana is now all but illegal, both in the States and here in the UK.

But possession isn’t – and a growing number of Brits are choosing to incorporate cannabis seeds into their diet to enjoy its astounding health benefits. Many even consider it a superfood. Let’s take a look at what exactly a cannabis seed contains and how its nutritional contents can contribute to your wellbeing.

Understanding Cannabis Seeds

To clarify, there is no real nutritional difference between hemp seeds and cannabis seeds, even if the latter ends up growing into a plant that contains high amounts of THC.

This is because cannabinoids such as THC, the compound known for its psychoactive properties, do not exist in the seed. These compounds are only present in the stem, stalk, leaves and flower of the plant itself.

The same applies to other cannabinoids such as the popular CBD, as well as flavonoids, terpenes, etc. This is why cannabis seeds on their own aren’t used for therapeutic purposes. But what they lack in that department, they make up for in nutritional contents and general health benefits.

All of this is explained in great detail on Discount Cannabis Seeds’ post, The Ultimate Guide to Medical Cannabis Seeds. You can buy cannabis seeds from their website and choose from a wide range of high-quality weed seeds. Their range exceeds 3,000 different types of seeds, with discounts and deals available daily.

Cannabis Seed Nutritional Analysis

The nutrition contained in a cannabis seed is quite frankly incredible. Starting with protein, cannabis seeds provide a complete source of the nutrient as they contain all nine essential amino acids. Since your body cannot produce these nine acids, it needs to obtain them from external sources. Very few plants are complete sources like cannabis seeds.

On the outer shell of a cannabis seed, you’ll find most of its fiber contents. This is why you should opt for seeds that still have their hull intact. But even without the shell, there’s still a considerable amount of fiber available. Around 35% of a cannabis seed is composed of essential fatty acids, including omega 3,6,9 and GLA.

As if that wasn’t enough, cannabis seeds also contain iron, copper, potassium, zinc, magnesium, folic acid, manganese, vitamin E and a number of B vitamins, including riboflavin, folate, thiamine and vitamin B6. Furthermore, cannabis seeds are highly digestible. You can eat them cooked, raw, shelled, unshelled… the sky’s the limit.

Consuming Cannabis Seeds

That said, you don’t need to eat them on their own. For instance, you can roast them and combine them with another healthy snack, such as kale chips, to make your own “superfood.” You can also put them in boiling water after roasting them. Then, add in some spices and you have your own non-psychoactive cannabis tea.

A simpler approach would be to simply sprinkle them over other meals, such as yogurt, salads, smoothies, quinoa, etc. You can even grind them up into a fine powder to use as a protein supplement, flour or milk. But how does all of this contribute to your wellbeing? Read on to learn about some noteworthy health benefits of cannabis seeds.

Heart Health

Cannabis seeds contain omega-3 fatty acids, which are believed to improve heart health and lower your risk of developing issues such as heart disease and arrhythmias. Additionally, cannabis seeds contain arginine. This is an amino acid that turns into nitric oxide, which helps keep your blood vessels and arteries in good condition.

Skin Conditions

Cannabis seeds also have anti-inflammatory compounds. Given that skin conditions such as acne and atopic dermatitis can result from chronic inflammation, it’s possible that cannabis seeds may help alleviate common symptoms.

Acne is linked to omega-3 deficiency, and we know that cannabis seeds are rich in omega-3. The rich plant fiber contents of cannabis seeds may also help with atopic dermatitis.


Healthful omega-3 and omega-6 ratios, such as those found in cannabis seeds, can help reduce inflammation.

This is also true for gamma-linolenic acid, a polyunsaturated fatty acid with anti-inflammatory properties. So, we know that this can benefit your skin, but the anti-inflammatory effects of cannabis seeds are far-reaching.

For instance, reducing inflammation can help with a number of chronic diseases. This includes metabolic syndrome, arthritis, heart disease, fatty liver disease, and type 2 diabetes.

Weight Regulation

Cannabis seed-based diets have reportedly helped people regulate their weight. Being loaded with vitamins, minerals and nutrients, cannabis seeds can help people with a high BMI stay full and healthy throughout the day, allowing them to lower their weight. The same applies to those with a low BMI who want to gain weight.

Overall Nutrition

It’s clear that cannabis seeds provide an astounding amount of nutrition. This is even more significant when you consider that all of it is natural, unlike commercial multivitamins and dietary supplements that are usually made of chemicals. For most people, maintaining a completely balanced diet among their busy lives isn’t easy.

Cannabis seeds can help by tending to your nutritional needs and eliminating any deficiencies, ensuring that your overall physical and mental health is at its best. Since there are so many ways to consume them, incorporating cannabis seeds into your diet isn’t difficult, making them an easy way to stay healthy.

If you’re looking for a natural and reliable way to ensure that you’re getting everything your body needs from what you eat, cannabis seeds are a considerable option. Now that they’re legal to buy and own in the UK, there’s no better time than now to give them a shot.

Which are the best nutrients for marijuana seeds?

Nutrients are the compounds that the plant absorbs in order to build its tissues and perform the metabolic activities necessary for its survival. Carbon, oxygen and hydrogen are assimilated by air and water. The rest of marijuana nutrients are taken from the substrate and the nutrient solution. There are different types of nutrients and these can be grouped according to the proportion needed by the plant. In this guide we will group them into macronutrients, secondary nutrients or micronutrients. We will define in detail each of the macronutrients and the typical deficiencies and excesses that may occur.

Primary or macronutrient nutrients: nitrogen, phosphorus and potassium

The nutrients that the plant consumes in largest amounts are called macronutrients and are nitrogen, phosphorus and potassium. All three are mobile, which means that if they are lacking, the plant will take them from other parts of itself. If this occurs, the effects of this deficiency can be identified in the older leaves.

Each of the macronutrients will be analyzed in detail, as well as the typical deficiencies and excesses that may appear.


Nitrogen (N) is the most soluble of the macronutrients, meaning that it leaches the most easily and can be assimilated by the plant most rapidly. Because of this, it is necessary to replenish this nutrient regularly. It often appears in the form of nitrates, and various ammonium compounds. Nitrogen is the major component of growth fertilizers and is necessary for the synthesis of nucleic acids and essential amino acids needed for the formation of new tissue,.

An excess of this nutrient causes an increase in the internodal distance, a stretched or ‘leggy’ growth pattern, with dark green leaf coloration. In addition, the excess growth promotes soft tissue susceptible to attack by insects or fungi.
To solve a problem of excess nitrogen, simply perform a root wash (leach) with twice as much water as the plant container has. We can also leach until the EC of the drainage water is less than 1.6 – 1.8 μS / cm.

A lack of nitrogen causes the oldest leaves to turn yellowish in colour. The nutrient is mobilized from these to the newly formed tissues producing inter- venal chlorosis (yellowing between the veins).
Nitrogen deficiencies produce pale green or yellow plants with little growth vigor.
The deficiencies in this case are easily corrected by adding growth fertilizer to the irrigation.


All living things make use of phosphorus in the form of ATP (adenosine triphosphate), a nucleotide with a high energy bond that is released when the phosphate bond is broken. This element, besides being essential for the energy of the plant, serves many other functions in plant physiology, especially in the production of resin.
ATP is used for photosynthesis, it´s a component of the DNA chain and is particularly essential in germination, cloning, seedling and flowering phases.

Excess phosphorus is often identified late, as the plant makes much use of this element and can withstand high levels. The most notable characteristics of an excess of phosphorus usually present as deficiencies of the elements zinc, iron, magnesium, calcium and copper. The most common symptom is usually the chlorosis of the veins with burns at the tip of the leaves.
To treat phosphorus toxicity, leach with a complete but very soft, (very diluted) fertilizer solution, around 5-10% of the normal amount, using a triple volume of water to leach the volume of the growing medium.

Lack of phosphorus causes developmental delays, with smaller, bluish-green leaves. Necrosis spots will appear and the stems, main nerves and petioles acquire a purple colouration. Later the leaves will start twisting and fall.

It is especially important to look out for a possible lack of phosphorus, since it will cause a delay in flowering, and the flowers will be smaller and not very numerous.

In many cases, the deficiency is caused because the pH of the irrigation water is above 7.00, values at which the absorption of phosphorus is limited.


Potassium, among other functions, is involved in the processes of carbohydrate mobilization, helps in the synthesis of proteins, and is essential in all stages of the plant.
It promotes the development of roots providing more resistance against fungi and bacteria.

Excess potassium is difficult to detect since the effects of toxicity hinder the absorption of other secondary nutrients and trace elements. The plant thus acquires the appearance of a lack of the elements whose absorbtion have been slowed. Likewise, the confusion can be reversed, so that a lack of magnesium, manganese, iron and zinc, leads us to think that there is an excess of potassium. However, this can be corrected by leaching with a solution of complete fertilizer diluted to 5-10%, that is, the solution is prepared by adding one tenth of the recommended dose and using a volume of solution that is three times the volume of the container or planter.

The lack of potassium is not initially detected, as the plants retain their appearance as healthy specimens with small spots of necrosis on the leaves that turn a dark yellow colour and fall after curling upwards.
The deficiency may be due to the accumulation of salts at the root level, since it is present in almost all soils and substrates. To treat the problem is leached to entrain the salts and then a complete fertilizer is added.

2. Secondary nutrients: magnesium, calcium and sulfur

The secondary marijuana nutrients are magnesium, calcium and sulfur, the salts of which are present in tap water. They are also known as trace elements or microelements, are indispensable in the synthesis of chlorophyll and participate as catalysts in many metabolic reactions. They are needed in very small quantities and it is very easy for excesses to occur. These deficiencies are common occurances in grows in which reverse osmosis water is used. This problem is usually corrected by mixing the osmosis water with running water until the electrical conductivity has a value of about 250 μS / cm.

Magnesium is the element at the centre of the chlorophyll molecule and plays an essential role in the transformation of light energy into vegetable matter. Excess magnesium is not easily detected, but it is also not frequent. When magnesium reaches toxic levels, conflicts with other ions, especially calcium, occur. This is the only real issue it can cause. Magnesium deficiency is common in acid soils, where the pH is less than 7. It produces yellowing between the leaf nerves between the fourth and sixth weeks of growth, although aside from this the plant will appear healthy. Then the tips of the new leaves will burn, and bend upwards. This problem is solved by adding one cup of dolomite limestone to every four litres of substrate in the initial transplant blend or by adding Epson salts at each irrigation.


The calcium needs of cannabis are almost as high as those of the macronutrients. It is the element that maintains the stability of the cellular membrane helping the correct transport of nitrogen and sugars. An excess of calcium prevents the correct absorption of potassium, magnesium, iron and manganese. Special attention should be paid to overfertilization at the beginning of the plant´s life, since it could impede correct development. Deficiencies are fairly common in industrial hemp crops but rare in self-cultivation; they are also quite difficult to detect. Abnormally slow growth is one sign, with yellow areas in newly formed tissues, weak stalks, and an inhibition of correct inflorescence growth leading to a lower yield. To treat a deficiency of this element we recommend a teaspoon of hydrated limestone for every four litres of irrigation water.


This nutrient is essential in the synthesis of amino acids like cysteine ​​and methionine. It is also part of vitamin B1 and many hormones.

Excess sulfur with low conductivity levels usually presents no problems. However, in cases of high conductivities, high levels of sulfur blocks the assimilation of other nutrients.
Symptoms of excess include limited development, small-sized leaves and dark green stems. The edges of the leaves may appear burnt.

To treat this toxicity, a leachate is applied with a very diluted fertilizer solution, ensuring that the volume of leachate is at least three times the volume of the container used.

The deficiency causes the leaves to turn yellow between the nerves, losing turgidity in a similar way to a lack of nitrogen. The tips of the leaves twist down and burn, beginning with the oldest leaves first.
This is normally a symptom of too high pH or an excessive amount of calcium.

The treatment for sulfur deficiency is to lower the pH to 5.5 – 6.0, and add inorganic sulphur to a fertilizer containing magnesium sulfate. Animal manure is a good organic source of sulphur,

3. Micronutrients

Also called trace elements or microelements, these are indispensable in the synthesis of chlorophylls, and act as catalysts in many metabolic reactions. This group of elements is composed of zinc, manganese, iron, boron, chlorine, copper, cobalt, molybdenum, silicon, nickel, sodium and fluorine. They must be present in minute quantities, and excesses can easily occur. Hydroponic fertilizers are often helpful because they have a balanced proportion of micronutrients. The microelements that are often under the desired limits are zinc, iron and manganese. This deficiency mainly appears in crops whose soil or water has a pH higher than 6.5.
