is it bad to trim my bitch in flowering? starting 2nd week tomorrow. first time growing id figure the lower branches i cut off was sufficient enough but it seems like its only getting hairs up top and focusing a lot more up top.... the lower branches i cut off about 1/3 of em and left the last 2/3's but i still think i should trim more since they arent getting light, is the bottom half a waste? or should i just leave it?
