You're not too far from me, maybe it's something in the water. Take it from me, The Black Hand of Death, I'd suggest using distilled water if you haven't. The stuff I purchase has a ppm of 10 and a PH of 6.

This is what I found in my limited experience. The 3 or 4 times I've used unfiltered tap water (ppm 200) and used more than 2/3 of the reccommended amount of nutes something bad happens. The two times I used filtered tap water (ppm 100) and used 3/4 of the nute level and didn't have a problem.

Someone correct me if I'm wrong on this. If you are going to use tap water let it sit 2 or 3 days so the chlorine dissipates.??
