I was trimming a few leaves from the ladies today and saw a huge difference in the need for trimming. The Sativa's hardly needed any trimming, while the full Indica's leaves were getting very wide, so I just trimmed a few lobes off of them to allow them to continue producing energy, and by allowing some extra light to hit the lower bud sites, they are getting much wider. I have a Black Diesel and a Train Wreck going, but the yield isn't too great because they stay too short with a heavy canopy and not mch underneath. Even with pruning, it never seems to produce well. I'm going to try some gibberellic acid around week 6 of vegging to try to coax a little more length out of them, hopefully encouraging side growth, like Sativa's grow.
