You want a total ppm, not individual.

I'm currently having the same conversation with another grower. Go into the Plant Problems section and look for a thread " buds not getting as big as I think they should ". A lot of info there......

I'm curious as to the ppm ranges necessary, or, are most beneficial in a soil/hydro system. I get my water from one of those windmill water stations and it test at 11 ppm. I mixed my amendents per gal. just to get a reading. CalMag alone, at 5ml/gal gives 240ppm, 7.5ml/gal - 340 ppm, 10ml/gal - 450ppm. Which level is best for early/late veg, early/late flw? Also the fets. FloroNova gives ppm near Rating: 5
