indoor fox farms light warrior with nothing added. i dont know the soil pH but i can check the run off later if you guys think it looks like a pH thing. i use tap water with a pH of about 6.8 on average. the plant is a 2-3 month old clone in a 5 gallon pot. it is a couple inches away from 2 24' t5's. ive probably only fed the plant 3-4 times ever with botanicare nutrients. the temperature stays at about 78 and the humidity is around 45%. a small fan is providing plenty of ventilation.
