Hijacked Grow

We're at 29 days from germ and its been an interesting week. The two plants are giving vastly different experiences. Mellow Yellow is much leggier and already flowering which caused a bit of a calcium deficiency, I've been giving calmag for the past few days as soon as the leaves started showing spots. The LST has been working very well on this plant because of how quickly the branches are growing. Big Red is an absolute bush now, not growing up as quickly as yellow and only just barely showing signs of flowering. On the flip side, I've taken fistfuls of leaves off of the underside and you can barely tell because of the growth its putting on. I'm curious if I should defoliate more as I'm barely able to keep air flow flowing into the under canopy as it is. on a slight concern is when each plant will finish as I am planning to use the tent to dry in as well. I think it will be ok as I am starting to see buds develop which only puts it a few days behind.
