Move your best girl's into bigger pot's as soon as you can.Run PH balanced water thru the soil for atleast a week(no nute's),you may want to consider a flush..Keep your light's a lil higher for now since the plant's are weak.If you have to lose a cpl plant's to make room then so be it.
Also think about using General Hydro 3 part,that's what i use for soil and hydro,it's easy and work's good.
