go 2 home depot and get a ph meter and maybe a moisture level meter,in the garden section., sink water usually has a high ph (above 7) which is 2 high, u want 5.5 to 6.5 try 2 find a ph up, and down, (read all directions on bottles), moisture meter should read around 1500, i heard 2000 is too high, and like tom 420 said, i would move the lights closer, maybe 4 to 8 inches from tops. and move up as plant grows.
