spider mites
root rot
nutrient burn, which is on account of elevated water transpiration
white powdery mildew, which is a results of an excessive amount of humidity
Wilting, which is a results of lack of sufficient oxygen
Buds that lack odor. This as a result of terpenes burn away at excessive temperatures
Increased stretching

Do marijuana plants cease rising at sure temperatures?

The excellent news is marijuana plants don’t cease growing when there may be an excessive amount of heat. However, their development will decelerate. It is because a lot heat impacts the means of photosynthesis. The actions of the enzymes are additionally stunted, and the plants produce only a few proteins.

For the sugars to be distributed all through the plant, the plant temperature must be above 20ºC or 60ºF. Within the case of sugars, heat is an efficient factor. If the plant isn’t heat sufficient, the sugars might be caught, and the plant will undergo. Once the plant is heat sufficient, the sugars can be distributed to their respective locations.
