Aye. It’s hard to say! I don’t do it any more because you never know the outcome until it’s too late!
I’ve topped autoflowers with great success! And increased my yield!
However, I’ve also topped them and totally stunted my yield, and the two mains grew extremely slow and short!
So—- you never know the outcome until you do it!. Sorry for the ambiguous answer! ✌️🏻💚🌿💨
