I just read that TUMS could be used for calcium - has anybody tried this? If yes, how many per gallon?

I started using Magical by technaflora and like it. 2% N 3.25% Ca 1.25% mg .11%Fe
Apparently they send out a lot of free samples to hydro shops, so I would ask if they have a sample bottle for you
