Please help... drooping leaves 3rd week veg

hey guys, first post here, but i need your help. two of my gals have had droopy leaves lately. i use miracle grow organic potting soil (i know i don't need to hear miracle grow sucks). two days ago i have 1/4 strength ferts to boost them a bit which it seemed they responded alright to. i just watered today and am concerned why two look like shit and the other two are ok. i have a 250watt hps lamp approx. a foot away from the tops. the only thing i can think of now that i've been looking around is it may be over watering. as you can see, this is a tiny grow, so i'd hate to lose any of my girls. any/all help is much appreciated!

cheers!

Every 2 days is WAY WAY too much water. That MG crap holds water like its cool. You are drowning them and dont even know it. You are nute burning them also.

No nutes for the next 3 weeks...AT ALL!! Dont water again for at least 4 days, then give them 8 oz each of plain ph'd water.

thanks man.. the more i look around, the more i think thats what the problem is. fuck i wish i didn't water them today.
