The yellowing seems to be getting worse. Please help. I'm feeding it nothing but fiji bottled water at this point. It also seems to be growing REALLY slowly. I'm only using a 150 watt CFL in a reflective dome that is literally two inches from it. I can't really afford anything that expensive at the moment. Can you recommend a better light I could purchase at home depot or lowes. This light seems to be really BLUE should I get one that is more yellow?
