I'm a new, first grow. I'm growing a couple autos and a couple feminized photo plants. I'm using TGA soil in air pots, bottom half filled with TGA super soil, top with TGA organic soil. The two photo feminized plants don't seem to be doing so hot. They have only been in the soil for 3.5 weeks but a couple of the leaves are completely brown. I was thinking maybe nute burn from the super soil but wouldn't think the roots would be deep enough yet. I can't imagine it is nute deficiency yet. Any help would be appreciated. Pictures aren't the greatest, will get some with the lights off. Still working on getting the pictures loaded...
