So I also got another , well something I just don’t understand, thought may be you could answer ? I used rainwater 20ppm Aprox 7.3 ish most times , I would add 2 ml of calmag and 6 ml of pure blend pro grow it would bring my ppm up around 800 ppm - now fast forward to me using tap water ( not sure of the make up yet ) it runs 300-400 ppm so no calmag but I have to add almost 12 ml of the pbpg to hit my 800 range ? It just seems backwards to me and I get the water make up thing but how can the nutrient bleep bd the same when I physically add more? Is it a reaction to something in the water ? I’m not to worried about it as I’m switching to mega crop this next run. I just really would like to understand
