Can i use 125ppm water from my tap or is the PPM slightly to high? I also dont have any Cal/Mag in my water cause of where i live.
I just recently finished a grow with tap water at 358 ppm. With spikes up to 7.6 ph. It can be done. I never used cal/mag with the high ppm. I might would consider it with a ppm that low. I live in a small town where nosey people pick up on every move you make so I didn't want to risk trips to the r/o water dispenser.
The ppm being 125 is perfectly fine but if it doesn't have any Ca or Mg then what is in it? There's 125 ppm of something, in most people's tap water these two elements would make up most of that
