Not sure if this is a issue or not. My ppm was at 1100 2 days ago.it slowly jumped to 1300 in two days. I just poured 10 gal of pure or water dropping the ppm down to 920. I noticed the next morning it went back up to 1050 ppm. I'm running a ebb n flow all hydroton system. Second week of flowering 18 buckets. Drinking about 5 gal of water a day.
