Well, I made the mistake of asking this out in the general hydro forum, geting views but no answers. Since I know you guys are opinionated and not afraid to post, I figured I'd post again in here.
Here's the original post:
"Finally got an RO unit and dropped my 325-350 PPM water to +/- 10 PPM and am about to start the first grow with controlled water, so I have a question. I run full hydro RDWC.
I've heard arguments for supplementing all RO grows with Cal/Mag and the opposing argument that using GH Flora series nutrients in a non-Lucas method that there would be enough calcium and magnesium in the 3-2-1, 2-2-2, 1-2-3* ratios.
Can anybody help to construct a good case for either side? I realize that different strains may prefer more or less cal/mag, I'm just looking for a baseline. "
* TSP/Gal. In ml/G, it's 15-10-5, 10-10-10, 5-10-15
