No I don't think so. The fan leaves are yellowing and turning brown. They also seem a bit brittle. She is using Foxfarm Organic Ocean Forest Potting soil with GH Hardwater Floro Micro and GH Florobloom for nutrients. PH is kept at around 5-6. I suspect it is about 5 or 6 weeks (maybe more?) into the 12/12 cycle. She has a 450Watt HPS and the plant is about 12 inches below it. I thought maybe at first it was too close to the light but the fans keep it pretty cool.
