Types of burns on cannabis plants

Light burns are one of the most common in cannabis cultivation. It is normally produced by the short distance that exists between the bulbs and the plants. For this reason, it is important to know the correct distance at which the lights should be placed and the power of your lighting system.

What are the symptoms of light burns?
The main symptom is a yellow decoration, usually in the center of the leaves or closest to the light source. Although there are many reasons for a discoloration, it is easy to identify because in the areas of the leaves farthest from the light it still maintains a healthy color.
On the other hand, when the crop is in the flowering stage we can recognize burns when the bud turns yellow, with small brown hairs, and thanks to the loss of some agents, it releases a very intense smell. It should be noted that in outdoor crops a plant that is very well hydrated does not usually suffer sunburn.
Burns by the wind
The first thing to take into account is to know if it is a cold wind, although you should bear in mind that any high intensity wind is not very beneficial for growing cannabis.
What are the symptoms of wind burns?
Normally, burns caused by the wind cause a curve in the tips of the leaves in the form of a slope, that is, they acquire the shape of a claw and their edges become discolored and burned, becoming so fragile that they fall apart just by touching them. . It can only be solved in some cases, placing an obstacle that hinders the impact of the wind on the leaves.
The main problem with the wind is that it causes a lot of stress on the plants. Although they are healthy, this stress tends to transform into burns. The best thing you can do is move it around in case you have it planted in a flowerpot. If not, you should look for other options.

Burns from excess nutrients
Although having your cannabis plants nourished is highly necessary, it can also be a factor that causes burns if you tend to overload them with nutrients. Keep in mind that, when plants feel stressed, they will manifest their state of stress through the leaves, either with spots or burns.

The decorations on the tips of the yellow leaves is the main indicator of an excess of food. Once this signal is detected, it is best to generate a control with meters pH and EC meters, in turn working with very high quality water, preferably with a Balanced pH of 5.5 and 6.5 free of contaminants.
We have to combat this excess by watering several times with this water at different times of the day, combining it with an enzyme complex that eliminates dead roots and facilitates the absorption of nutrients accumulated in the substrate.
Following these steps, it only remains to observe the evolution of the plant, it should return to the lively color without burns that it had previously. If you want to ensure a full recovery you must continue with the controlled diet.
Burns from overwatering
Burns caused by excess irrigation are the most difficult to identify because they are often confused with other symptoms. To detect an excess of irrigation you have to combine some symptoms such as burnt tips, by means of a soft fertilizer, and that the pot does not lose moisture.

The cultivation of marijuana tends to be decayed and with yellowish leaves, but pointing upwards. Normally the roots look a bit rotten if we dig into the dirt. To avoid this condition, an explicit water control is recommended for each stage of development, ideally, the substrate should remain moistened for 1 to 3 days and only water when the pot has lost half its weight.
