Every thing is looking good. Looks like you may have little clawing on some of those leaves, not to much to worry about. It could be a little to much N in the feed for flowering. Dail it right back for next couple of feeds with plenty of run off and see if you see any change in the tip of those leaves. You can often tell by how dark the leaves are as well. Your out side plant is looking a better colour.
I think you should be alright on size, your using CFL so they can get close to that light.
I know your watering every other day but are you using the pot lifting method of when to water. The drying out of the medium is quite important. It can effect yield if you don't let them drink up. It takes a bit of judgement, for soil you want a light pot (lift with one hand easily) for coco you want it a little heavier (never let coco dry fully dry out like soil).
Hope your having good a day
happy Thursday
