I sometimes want to prune the plant so the lower and inner buds get more sun light. But I heard that hurts the plant more than it helps. I usually try not to pull off any green healthy leaves. I like to keep my plants leafy. I heard that the leaves are like solar panels for the plants energy. So the more solar panels the better. If I see any bug damaged or yellow leaves I will usually pull them right away though.

I have heard that you can use neem oil a few days before harvest. I am not sure if it effects how your bud taste or not though...
