are they still without any pistols,what i mean in veg mode,are you giveing them any nutes i would reco nutes if ya wanting a good yeild.You want the watering to be so the medium is wet but not like sludge,then allow to get dry don't water every day just when they dry if it aint dry don't apply.
That is why i would all ways start of in small pots then re pot once root bound into there final pot but let them get to a decent size before re- potting
Just wet the plants through and allow to dry and they will be fine but you must let them dry out its key to getting good root structure
