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 good news is marijuana plants don’t cease growing when there may be a lot heat. However, their progress will decelerate.

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 will not be heat sufficient, the sugars will likely be caught, and the plant will endure. Once the plant is heat sufficient, the sugars shall be distributed to their respective locations.
