Hey all
I live in a part of Canada where our groundwater is extremely rich in Ca and Mg naturally, and I'd like to utilize this in place of synthetic CalMag additives. However, natural PPM is 350 out of the tap.
RO water works perfectly in bringing this down as low as needed with simple additions, so my question is, what is the ideal PPM for a coco and soil grow, both? I'm experimenting with both.
I figure the soil is much more flexible but would still have an upper limit before it calcifies. And the coco is probably much more important to keep in check.
I have meters and would like assistance, thank you!
