Order of testing and adding Mag,alk,ca

[undbulsu]

Does it matter the order of the three? I seem to remember reading that you should test Mag first, add to bring up to the level you want, then Alk, then Calcium. I’ve been following this protocol but was wondering if this is correct and why?

Unless any are severely depleted, the order doesn’t matter. If magnesium is severely depleted (very rare) then supplement it first. Order of the other two never matters. [emoji3]
