If my ppm is too high, will that screw up my ph? I seem to hafta flush em frequently ta git the runoff back into the 6-7 range. It's at 6.3 to 6.6 when it goes in, but have never measured ppm before. Water is at 300ppm, am using Dyna-grow 1/4 t per gallon, never measured so don't know what it is, just got tds meter hopeing it'll cure my problem. Thanx fer the help, Can't afford ta fuck this up!
