Plants don’t have a mechanism to deal with “overfeeding,” and so plants taking in more nutrients than they can handle get sick. There are a number of reasons that might happen, including unrelated illnesses or pests damaging the plant. It could also be the result of an environment that’s simply too nutrient-rich, to begin with. In any case, a plant receiving an overabundance of nutrients will begin to suffer from nutrient burn, and, left unchecked, the consequences can be devastating.

Early warning signs:
Nutrient burn symptoms start at the tips of the leaves because as excess nutrients build up, the plant attempts to pass them along, and the leaf tip is the furthest that they can move. Therefore, it’s important to keep a close eye on changes to a plant’s leaf tips to ensure nutrient burn is caught as early as possible.

Before more balanced fertilization can be applied, the overabundance of nutrients already built up need to be flushed out. In a hydroponic setup, that entails emptying out all reservoirs and filling them up with pH-balanced water. That water should be run through the system for at least 24 hours, with the system’s electrical conductivity (EC) levels being checked daily until the proper fertilizer salt levels are reached.
While some or all of these symptoms will be present in a plant suffering from nutrient burn, curling leaves are often an indication of an overabundance of nitrogen, in specific. As soon as these more advanced symptoms are recognized, growers must isolate the nutrient burn and fix the source of the over-fertilization to prevent further damage.

  • An extreme deep green coloration to leaves
  • Bending at the tips of leaves
  • A slight yellowing or browning at the very tips of leaves

Flush out the growing medium:
Lighting should also be checked to ensure plants aren’t being under lit, as a plant getting less light generally won’t require the same level of nutrients. In that case, nutrient burn is actually a symptom of a lighting problem, and adjusting light levels will unlock additional nutrient capacity and better growth.

Spotting And Resolving Nutrient Burn In Your Indoor Growing Operation.

Mineral-based nutrients can help increase cannabis growth rates and yields compared to organic-based nutrients due to the fact that these nutrients are so easily absorbed by the plant roots. The plant doesn’t have to do any “work” to get the nutrients. The downside is your plant can easily take in more than it can use if the nutrient levels are too high.

In hydro, once you change the water and lower the nutrient levels to an appropriate level, you should immediately notice the nutrient burn stop spreading. Old leaves won’t recover, but you shouldn’t notice any leaves getting worse.
This is wrong, instead nutrients are more like a multi-vitamin for your plant. Just like you can’t give a child 10 multivitamins a day to make them grow faster, you can’t give your plants 10x the regular does of nutrients and expect anything good to happen.

Problem: You will notice the tips of your marijuana leaves showing the first signs of nutrient burn by turning yellow, tan, gold or brown. A light case of nutrient burn will only affect the tips of your leaves.
(Nutrient burn is often called “Nute Burn” in the cannabis growing community).
Your leaves are like solar panels, and the energy produced by the leaves is used as energy for the whole plant. You need the leaves to be in tip-top shape to get the most energy from the lights, so your plant has plenty of energy to grow and produce buds.
These Plants Are NOT Overwatered, These Leaves Show Signs of Nitrogen Toxicity
Cannabis plants spend the beginning part of their life in the vegetative stage. When cannabis plants enter the second part of their life, the flowering stage, they stop focusing on making leaves and stems, and put all their focus on making buds/flowers.

The yellow tips will eventually turn rusty brown and crispy. If you do not correct the problem, you may also notice the burn slowly spreading from the tips to the whole leaf. At this point, if you haven’t done so already, you should immediately treat your plant (directions below) before there’s more damage.

Nutrient burn causes the tips of cannabis leaves to turn yellow or brown. The burnt tips are the result of too-high levels of nutrients. Learn how to fix it!
