Thanks. I'm growing organic in soil with RO water, I shouldnt have to worry about pH anyways really. I hardly ever use the meters. I just wait 24 hours to feed after mixing nutes since I know they drop the pH quite a bit. Basically just a compost tea if you look through the ingredients. guano, kelp, molasses, etc.those cheap ph meters #s are worthless, just like run off .....................obviously you need to supplement cal/mag with RO, but it is a fine line.
good luck
Regarding calmag, just using elemental and sticking to recommended dosages from Roots Organics. A lot of people use tap water and dont run into cal/mag deficiencies so they think its not necessary.
