Fertilizer burn is a problem many beginner marijuana growers encounter. Fertilizing is necessary and good but over-fertilizing your plants will result in severe fertilizer burn. In this article, I’m going to explain what marijuana fertilizer burn is, and look at the ways of preventing and treating one.
What is a Marijuana Fertilizer Burn?
It’s better to perceive your marijuana seedlings and flowering plants as small babies. Growing and development is a slow process, and giving more nutrients won’t make that process faster. In fact, it can do more harm than good. If you will overfeed a baby, it will be irritated and it will throw up.
Unfortunately, the plants can’t throw up the stuff they have absorbed, they can only express their irritation. Marijuana fertilizer burn, also called „nutrient burn” or „nute burn” appears as a result of over-fertilization or when fertilizer has been applied to wet foliage. Fertilizers contain salts which can dehydrate the plants. The edges of the plant leaves turn yellow or brown, the tips get crispy and twist. The growth slows down. Roots also can suffer damages. Besides, the damage can increase dramatically in a hot and dry environment.
It’s worth taking into account that fertilizer burn can also appear if the plants are grown in a soil that already has high levels of nutrients.
The symptoms of marijuana fertilizer burn may appear in a one to three day time, if it’s a light over fertilization. But if you have used the fertilizer excessively, the symptoms will appear sooner. However, if you’re using a slow-release fertilizer, it may take a couple of weeks for the problem to appear.
If the problem is not dealt with as soon as possible, the burn will slowly spread from the tip of the leaf throughout the whole leaf. In the worst case scenario, the plant will start dropping leaves, thus, losing its leaf mass. Consequently, this process will slow down the growing and development, finally resulting in lower yields. Moreover, the excess nutrients may give the buds a nasty taste of chemicals.
How to Prevent Nutrient Burn of Cannabis?
The best way of not having to deal with a problem is a successful prevention of it. Even a beginner marijuana grower can avoid having the problem in the first place. Here are some simple tips to keep in mind and apply while taking care of your precious marijuana plants:
1) Never apply fertilizers directly on the leaves and the stalk of the plant. The opposite is a shortcut to causing a serious damage to your plant and affecting the future yield.
2) Never mix your fertilizer while holding it next to the plant, and also don’t keep fertilizers next to your plants. If you accidentally will spill the whole bottle on the plant, you will have only 1-3 hours to rinse the soil before the plant dies.
3) Fertilize each plant, taking into account its needs.
4) Using a slow-release fertilizer may significantly reduce the possibility of fertilizer burn because the nutrients are released gradually.
6) Control the temperature and humidity in the grow tent. The fertilizer can become more concentrated in the soil if the environment is hot and dry.
How to Treat Marijuana Fertilizer Burn?
If you have failed at preventing the marijuana fertilizer burn, shame on you. There are not many steps you can take to treat it and everything depends on how well you will do the necessary steps to help your plants recover:
1) Stop adding fertilizer, and give your marijuana plants time to use up the nutrients.
2) If the damage is serious, scoop out some of the over-fertilized soil, rinse it with pH-balanced water, and put it back.
3) If the damage is severe, rinse the whole soil with as much water as the pot allows and let it dry. If possible, do it with pH-balanced water. This will let the roots recover and use up the rest of the nutrients from the soil.
That’s it, folks. That’s all you can do. The best ways, in the end, are adequate care and prevention. Take good care of your marijuana plants and grow smart.
