and i know its hard to tell, becuase of the 1000w HPS lights, but in the first picture the leaves are turning a purple-ish brown. please help!


also, i have a 20lbs Co2 tank, which i dont have a regulator for yet. so i just open the valve for a few seconds every night, idk if this could be causing anything, considering i dont know how much co2 im actually putting in the air.
