i have been pruning in veg (i guess not enough) and went into 12/12 3 days ago. i pruned a couple of days b4 going 12/12, but i see now there will not be enough room when these ladies stretch... ( 2 headbangers,1 sdkush 2 somangoes) - do i just bend the tops, or can i prune off a good 6/8 inches ... thanks
