I grow in hydro and wondered with a cal/mag deficiency how often should I add the cal/mag to the tank? I am using sensi bloom cal mg and it implies to use constantly

If I am trying to overcOme a def. I use it double strength.

I always keep 250-400ppm of sea salt in my rez, as that adds the Ca and Mg that I need plus 80 other elements that you don't find in commercial nutes.

Could you also use the sea-salt for soil?
