​How old are they and what type of LST would you attempt at this point?
Time for lst! Bend them down, no breaking allowed, between two large fan leaves, try to get angle least a 45 degree bend. Let that set for two days then do it to the new growth. When new growth starts at node 2 and three then bend it 90 degrees away from the center stalk to allow light in. Keep going with notes 4 and 5 until two or three weeks into flower. Goal is a canopy with all branches at the same height.
