What kind of light are you using? That is crucial information.

oh woops, its a 400 watt hps

try 6ish inches away. Check the babies for heat stress. (browing edges, curling up of the leaves) and move accordingly. HPS produce a lot of heat, you might want to put it even higher. notice if your stems seem stretched ... if so move closer. Hope it helps bud.
