Should i do defoliation?

Hey ! As you are growing autos, the less you defoliate, the better they will be. You can try to tuck big fan leaves at the canopy for a better exposure of bud sites if you think some of them are under exposed. You can remove fan leaves yellowing at the bottom, but the less the better. Whatever you do, remember that autos can easily stress, so go nice and easy. Hope it helps and good luck !
