Thanks for the help LEDMan. I'll get the Fox Farm nutrient trio from the hydro store this afternoon and see if they will sell me some reverse osmosis water while I'm at it (or buy distilled form the grocery store). I'm still worried that our tap water might have other stuff in it even if I can...

Soil: 50% Fox Farm Ocean Forest and 50% worm castings, no nutrients yet...
