Good call Snoop. Get some cal mag+, or for right now a teaspoon of epson salts in the rez. It will hold till you get calmag. Please use RO or distilled water if you don't know what your tap water has in it. My tap water runs just about 200 PPM's. It will kill a plant in no time even if I let it set for 24 hours to get the chlorine out.
