If growing weed outdoors, flushing may be an issue. But you can plant some side crops amongst your cannabis plants. Plant a crop like corn, which is a heavy nitrogen feeder. This will make sure there is less nitrogen in the soil.
It will be harder to removed any element in soils than it would in hydro or coco, as the drainage isn’t so good and you can risk overwatering your cannabis plants. It is best to do one big flush, to remove as much as possible from the medium. After the flush, let the soil dry out until the pot is light, before watering again.
Use a low nitrogen mulch, such as wood chip, or sawdust, as this will also leach nitrogen from the soil. Just cover the surface of you soil around the plants in a fine layer and let nature do the rest.
With an excess of nitrogen the plant wants to work hard building foliage, and stems, as this is what the plant uses it for. The more nitrogen it has, the more it will try and grow leaves and stems, rather than flowers. Your plant will grow quickly, but it will be weak and spindly.
Even though nitrogen is an important element, too much of it can cause problems with weed plants. If these problems are not fixed before the flowering cycle, your plant will struggle to build flowers, or the flowers will be airy and less dense.
Nitrogen is an important element of plant growth. Your cannabis plant will take it from the medium, and use to to build stems, branches, and leaves. It is also a major component in photosynthesis. Without it, your plant will no be able to make chlorophyll, which means, it will not eat.
If you dont have an EC meter, and youre growing in hydro or coco, you will need one!
Nitrogen Excess can have lasting health effect on your marijuana plant. You must be able to recognise the symptoms of a nitrogen toxicity, to ensure the best harvest possible.
How to fix a nitrogen excess will depend on the medium you are growing in. It can be as simple as flushing you medium, or, if growing outdoors, you may have to plant crops that will eat a lot of nitrogen. This will help remove some from the soil.

If you can’t order online and can’t find a good one-part base Bloom formula locally, you do have other choices. Though not an ideal choice, most Cactus plant foods will contain good nutrient ratios for growing cannabis during the budding stage. So in a pinch, you can use the cactus nutrients that can be found at most gardening stores.
Problem: Dark green leaves, shiny leaves, clawing, weak stems, and overall slow growth. Marijuana leaves that are nitrogen toxic often get “The Claw” or talon-like leaves that are bent at the ends. They also do an odd curving (or cupping) that is often mistaken for overwatering, but is unique to nitrogen toxicity. You can see a “clawing” leaf in the pictures below (click each picture for a close-up).
Some examples of good one-part Flowering nutrient systems…
The very first number, “3” in the case of the picture to the right, always displays the proportion of nitrogen in this nutrient bottle compared to the other 2 nutrients (Phosphorus and Potassium respectively).
Pretty much any complete plant food
Effected leaves likely won’t recover, but you should see the problem halt with no new leaves being affected.
In fact, nitrogen is one of the 3 nutrients that are included in almost every kind of plant food.
Most complete plant foods that you get at a gardening store contain high levels of nitrogen (N). These nutrient systems tend to work well in the vegetative stage.
Leaves that turn into claws often start turning yellow and dying if the nitrogen toxicity is not treated, much like a nitrogen deficiency, only the leaves will continue to get more and more clawed. Leaves eventually turn yellow or brown and fall off. You can tell if yellowing is caused by too much nitrogen because the rest of the plant will be dark green, and the yellowing leaves will turn into claws first.
Does your plant have "the claw?" The talon-like leaves that are bent at the ends are a sign that your plant may have nitrogen toxicity. Learn how to fix it.
