Yeah man lego man ! what's up, yeah looks like you got some good structure and nice growth ! personally i wouldn't really defoliate unless you really have to or like the leaf dies naturally like it turns yellow or something. So but you're right that you can defoliate and i could help. First rule is don't over do it man ! Technique is simple : you want to clear some space so that the secondary bud spots gets lots of light so it gets ready quicker. So take some off, or even part of some leaf off. So the best is to defoliate when a leaf is hiding another stem or bud from the light. Hope this helps man, looking good already !
