Have you sexed them yet? I would look back but I am half asleep. You may want to start trimming the one you are going to make a mother. If you dont want a giant plant you may want to take the two top fan leaves off of the top. The ones that are real small, I mean the size of your baby toe nail or smaller. But just the fan leaves at the stem leaving the growth. Maybe just one then wait a couple days then another so she doesnt loose to much fluid. She will bush out a bit. If you want to have more sites on the lower branches for clones they will need light. I would take off for now just one big fan leaf blocking light the most light to the lower branches.

One love
