Is Cal-Mag Plus a good product?
I had terribly hard water and used General Hydroponics Flora Series three part nutrient line with the Micro for hard water. My tap water was at about 330ppm, so I bought a high end Apec 5 stage R/O water filter. My ppms are now at 10ppm, but forgot to buy the regular micro. I think that my tomatoe plants are suffering from a calcium deficiency. They are about two weeks in my Areo/DWC system, and the leaves are curling up, inward and twisting. Will Cal-Mag Plus correct this problem? All condition are optimal including pH, TDS and temps.
