All of them do I think. Should have some iron too. I'm using REMO Magnifical atm and it's 3-0-0. 3%N, 2%Ca, 1.3%Mg and 1%Fe.I recently learned my calmag adds N , fwiw.
For the soil growing folks I'd suggest using dolomitic lime and agricultural gypsum mixed in with your soil. No extra N and really no use for CalMag either and the stuff is dirt cheap. Nice dose of S in the gypsum too.
