dude got to get your mind out of this modern pseudo science butt fuck
thier are no organic macro or micro nutrients, only organically derived, most of which takes a long time to degrade to the point of usage, like greensand takes almost a year to break down, kelp products dont fully break down for at least 4 weeks . . and the list goes on
, calcium and magnesium in various forms are elements, not chemicals
i think roasted crab shells should be a organic cal mag derivative. but it takes time, if your deficient today it wont work like a bottled organic additive ready for absorption
please educate your self on soil e.c and cannon anon elemtn exchange and well as che lating agents (which i can not remember for the life of me right now)
