Hey screwie, What you screwing around at now ehhh :) Erm my opinion only ever defoliate if your freeing up light for buds. Never ever defoliate for anything else reason being your plant needs her fans :) its how she converts sun light to engergy and everry healthy leaf you remove is taking that energy away from the plant. you can defoliate to make air flow better too but I would only do so if your plant is healthy and growing well. if not it could stunt her more than a week or so in the end though im sure you know all of this. at the end of the day pal its your plant you do what the hell you want :)
