SO how do I calculate my tap water 220ppm in with nutes ? If I looking for a feed at 600ppm then it shud read 800ppm to be a correct feedThat is not bad. Keep that number in mind and when mixing nutes and you should have no issues. These are being fed Mississauga Tap water and they are doing just fine. View attachment 4753517
Yes, I just subtract the tap water value to get the nute ppm.SO how do I calculate my tap water 220ppm in with nutes ? If I looking for a feed at 600ppm then it shud read 800ppm to be a correct feed
But over all ppm Wud read 800 on meter. But u know your water has 200ppm so it’s ok cuz u only giving 600ppm of actual nutes ?Yes, I just subtract the tap water value to get the nute ppm.
