to prune or not to prune

[deliciouslips]

I'm a newbee...My ladies are in their second week of flowering. All very healthy and full of buds. My concern is there are lower buds that are shaded by growth due to larger leaves (fan) that block their light. My second concern is air flow. I have read, some prune, some prune lightly and some say DON'T PRUNE AT ALL. I would appreciate feed back from those who have experienced the same concerns and what they've done and why..and the end result.
p.s. love the smily faces!

Well,I had to do something...so I pruned...it was a bit scary to do but I figured I still had over a month to go till harvest. So far,all the ladies are doing well no sign of stress and/or stunt in bud growth. Because I have no idea how big the buds get on this variety I only wish I left 1 plant unpruned..so I could compare its productivity.I will know better next time....
