there in a hydroponic system, the ph is under 6.5 my ph test goes to only that, but i assume its around 6 cuz it was lighter then what it said 6.5 would be but not by much, the light is 28 inches away from the top of the hydroponic system and 23 inches away from the plant it is a 400w hortilux mh, i did however a week ago put in a tiny bit of miricle grow hopeing it would help the plant, and it did for a few days, and now it looks like shit, so i changed the water and didnt put any nutes in at all untill i can figure out what to do
