Guys please more help, do i need to defoliate them or at least the one in the left corner who was over watered? Or maybe topping or anythig that helps? Because i don't think it's auto, and it's huge to let her grow more till the others have enough nudes to turn the light in 12/12 cycle and the one who had spot on one leave is auto and she started to flower, it's very bushy and short, should i do some technique to have bigger yield and bigger buds, because i think when the plant is bushy like this the buds inside won't receive any direct light!!
RELAX!
I wouldn't defoliate anything at this point. You need to let them flower before you worry about the buds not getting any light. You could do some leaf tucking if you want more light to parts of the plant, but I'd wait until you have buds. You don't even know how much the plants will stretch once flipped. They look indica-dominant to me so hopefully they won't go too crazy. Some sative strains can easily triple in size. If you defol'd them now you'd wonder what the heck you did it for.
These little girls were flipped...
...and turned into this.
Let them dry out. Flip them. Learn what you can. Improve with your next run. It's all good.
