First, as mentioned, you should try LST and if that doesn't cut, wait for the final stretch and the take only the leaves that are blocking a larger area from receiving light, I mean if you have a fan leaf that is shading a larger area then the fan leaf itself, or is directly shading a bud, cut it. But remember, the more leaves she has, the better. In my experience, if you have a bud in shade but it's fan leaves are receiving light, the bud will fatten and ripe as much as the others receiving direct light. Have fun growing, tchau do Brazil! =)
