Hi everyone,
I have T. Pachanoi, T. Peruvianus and T. Bridgesii seedlings. They're about 2 months old. The tips of the Bridgesii seedlings are turning brown/black whilst the others are fine.
I know that red tips means too much light. I have them about 20cm below an 11W CFL with a reflector for about 13 hours a day.
Am I giving them too much light or not watering enough?
