Im a couple weeks into main-lining in dwc. My ppm with GH trio and well water is pretty low and stays rather stable around 550. The leaf tips have been curling under for a couple weeks and I thought it could be due to low night temps in my basement. However now the tips of some of the new growth is beginning to turn yellow and move down the leaf between the veins. Whats going on here? Too much food or too little. I used cal-mag at first but once she looked better i stopped (i think this might have been my mistake).
