Just pruned pre-flower

My 3 plants have vegged 4.5wks and they and ready for flower. I pruned the bottom 1/4 or so just to be a little on the conservative side.

I have 2 questions - can I still transition to 12/12 tonight or should I give them some time to recover from the pruning? Secondly, the large bottom fan leaves - should they come off too?

Yes, no

See attached. I put red spots on the fan leaves in question.

Personally I'd keep them as long as they are in light they are still helping

Edit: your plants look good btw

Thanks. Appreciate it. First grow, so this board has been amazing.
