Hi, Iam no big Fan of Defoilation. I always pick/tuck single leaves that block the light to the flowers. And i put away all small branches and tiny leaves/ flower at the bottom of the Plant. If you dont have big humidity issues i wont defoilate. But its always your descision. Remember, everything you take away, the plant tries to reproduce. My Light have a very fgood light penetration, so i only have to take away a few leaves. It depends also in your setup/ the Humidity and how bushy the girls grow
