ps,
For your next grow i would advice you to grow at a temperature of 25-27 degrees with humidity 80-90%, PH 5.8 with ec 1-1.8
and for flowering get 21-25 degrees, 45-50 humidity, ph 6.2-6.5 with ec 1.8-2.5 depending on size of the plant.
Why? because in my opinion your plants had many stretches and should had stayed lower so your lower colas would had had the same lumens(light).
and the quality of your buds would have been thicker and better. Make sure you put your lightsource and temperature(lamp in your case) not to high
because of that reason your plant will stretch and get fluffy buds as well.
But since you have high temperature now, i would advice to keep the humidity you already have.
if you can do something about it, you should.
