sprout at a stand still

stinky could you help me i am using 150 watt hps, good ventilation and the plant is nice and green i cant figure out why it wont grow is there some kind of nutes you can give to sprouts or do you think calmag would help i am using distilled tap water treated to 6.5

I would just use plain tap water at 6.7, not distilled. It might just be suffering setback from not shedding the husk fast enough. If it doesn't look discolored, droopy, burnt, whatever, it's going to be just fine.

thank you very much
