your lights are no where near sufficient to make it even worth growing those...also never plant more than one plant in the same dirt..... but dont fret just get a better light and repot those suckers in separte pots..... also I hope you know not to use ferts when ur plants are that small....... NEED MORE DETAILS like lighting etc... to give better advice.. is that an areo or dwc or ebb/flow or what?????????????????//
