Well im suprised there doing that well looks as light has burnt tham a litlle or a bit of nut burn.I personly use t5 for veg and 1000hps for budding.One thing you must do is give them each there own pot of soil 3 to 5 gal pot.If you wont any kinda yeald ate all your going to have to change the light sourse even a small 400 to 600hps would work but over all they dont look bade for the tools your useing wish ya all the luck and happy growing..peice out from humbold own:rasta:
