What should my ppm be for starting out? Iam very unfamilar with ppm. I purchased the truncheon meter. have yet to use it but i think im going to transplant 2 of the little guys today with a 1/2 nute strenght mix. So just to make sure im doing this right..... start with water then mix my nute 1 at a time, check pH, then check ppm. again what should my ppm be at?
