you really need to just let the plant do its thing, grow. by defoliating to many leaves you will f*ck up your harvest. Defoliation is good only if you dont take of too much. you do this earlier in veg and flower. after the plants get in the 5th week i would stay away from taking anything off. i would recommend just leaving your plants alone so you can learn how the plant grows as well as learn what you need and what you do not need. i know you want to listen to everyone who said defoliate and then you listen cause someone said it works, your growing an auto some autos dont like to be messed with, their job is to grow buds fast, and some of those leaves you took off, that bud needs sugars from that leaf. now imagine if you let the plant be, you may have gotten nearly double your yield. just leave the plants be to do what they need to do.
