hey man, what light schedule have you been running? has it been consistant? and how often do you water, and whats the temp of the area u have it in? if its just in a open room rather than a closet where the temp builds up it may be kind of cold w/ a mix of over watering. if its not relatively warm the soil can stay moist for a week or so. do the finger test. stick it down 2 inches and if its stickin to ur finger it can go a day. imo it doesnt seem to be a ph problem or overfert/ underfert problem because theres normally burns, yellowing or other signs. check that the lighting is about a foot or so away fromt the plants to absorb all that 250 watts (check w/ hand to make sure it wont burn it/ you), maybe get some mylar reflective too to absorb all that 250 low light can stunt growth.
check into all that, all i can say. oh and the one on the rights lookin good, jsut the twisted droopy leaves on the left catch my eye
