Hello, so I planted this seedling not expecting much out of it. To my surprise, I think it's done pretty well so far. However, it recently started really curling up, especially the older leaves. Then it really started to turn a nasty yellow and somewhat brown. It's about 14 days old, and I transplanted it yesterday (admittedly probably a mistake). I'm using a 150W LED grow light, and a mixture of Miracle Grow potting soil, bone meal, and compost for soil. I've been running the light nonstop, and only today did I turn it off for 6 hours. Also, I read that maybe the humidity is low so I laid out some pans with water to hopefully raise it. I have a fan as well that's blowing between the light and the plant. This is a closet grow, so air circulation is a problem, but I do try and open it up as much as possible. Please help, I'd really like to save this guy.
