spider mites
root rot
nutrient burn, which is on account of elevated water transpiration
white powdery mildew, which is a results of a lot 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 creating when there may be an excessive amount of heat. However, their progress will decelerate. It is because an excessive amount of heat impacts the technique of photosynthesis. The actions of the enzymes are additionally stunted, and the plants produce only a few proteins. However, whether it is uncovered to heat for lengthy durations, your plant would possibly find yourself dying.

If you’re rising marijuana in a develop room, keep in thoughts, the utmost temperature for marijuana develop tent success is 85°F. Temperatures larger than it will consequence within the plant’s demise.

When the marijuana develop room temperature is above eighty five levels Fahrenheit, photosynthesis will likely be affected; nonetheless, the plant will nonetheless produce sugar. For the sugars to be distributed all through the plant, the plant temperature needs to be above 20ºC or 60ºF. Within the case of sugars, heat is an effective factor. If the plant shouldn’t be heat sufficient, the sugars might be caught, and the plant will undergo. Once the plant is heat sufficient, the sugars shall be distributed to their respective locations.
