good to know. i have epsom salts coming and can make ca supplement with eggshells and vinegar if i remember correctly.

of course i could just buy calmag but wheres the fun in that

Got me, I don’t have time for that kind of stuff. Calmag will usually add a good amount of nitrogen, calcium, and magnesium. If you are treating for an individual deficiency there are probably multiple ways to do any of the three.
