Hey guys I have a 12 gallon res. With a 400 watt s.w. ballast veg. For 1 month and now for 52 days since I flipped the light. No LST or HST its 6foot this is my first grow. I'm using r.o water, supernatural bloom aqua, I have a 6in. Air stone directly below the roots I lifted out of the water the root ball is seriously is as big as a basketball. my heat it 79-81F, I have it in my closet and have a fan blowing across the light and another one on the bottom of the plant. The plant has stretch obviously an so will my buds be all fluffy and sh*t. They have alot white pistils except at the pistils at the internodes have turned brown and the calyz has swelled and the calyz have trichs and are starting to glisen (sp) when will my pistils change colors and it seems like there are not fat like you see on here. I have my ppm at like 1400!! So if the trichs are all over even leaf material how much approx. Do I got? I have a indica!!
