Growing up I've always heard that you should prune away the big fan leaves to maximize light to areas & increase airflow. This was obviously 20 plus yrs ago & I know things have changed so after reading about it online I'm left even more confused. My plants are at day 40 of flowering & are chock full of fan leaves, some of which are yellow or dying. Is it good to prune away these fan leaves so buds can get light? If so which ones? Or am I best off tying down the fan leaves in a way similar to low stress training?
