Hmmm, maybe the roots are in a pocket of nitrogen or something? Not sure if those tend to happen in Coco Loco or not. The other side is a little discolored and the new growth looks like it might be as well. Still just that plant. Wouldn’t be lockout this early, would it? I wasn’t pH’ing my tap water as I was using very little. pH of water was probably 7-8ish. Closer to 7 than 8 if I remember correctly.
