Great healthy looking plants you have there Widow! Have you thought about tying them open a little. I dont know if your room is full or how much space you are working with but if you tie strings around the bottom of some of the buds and gently pull away from the plant, it will open it up and let some light penetrate. The downside to doing that is your plant pretty much becomes stationary and you have string everywhere but its very little stress to the plant as long as you dont get carried away pulling. I prefer to do that over trimming leaves. Good luck and great looking grow!
