I have "That 70's Grow" and have been using distilled water for all plant needs, is their a problem switching to filtered well water. The Ph is the same 7.2 and the TDS on distilled is .002 ppm and the filtered well is .432 ppm, Thanks in advance 😉
432ppm is pretty high. Once you get the nutes in there and mix everything up you're looking around 700-900 ppm for a basic feed thats should be looking more like 300-400. Without knowing exactly whats in that water it could certainly cause problems down the road.
