I am in search of a cal-mag supplement. Do you carry some that you can recommend?

We have a couple different cal-mag supplements. Botanicare has Cal-Mag plus iron, this works well in soil or hydro systems.  We also have A few organic calcium and magnesium products.   Cutting Edge Solutions makes it I’m two separate products, mag amp and plant amp.  Also General Hydroponics makes a good one part it is CaMg+ it’s a good organic product.  FYI organic products tend to “muck” up reservoirs.  Personally I like organic.
