Microwave some egg shells, until they're dry and clean, then grind them to a fine fine powder and mix into your coco (like grandma used to do with her rose bushes!), for a bit of calcium, and dissolve a bit of epsom salt into water and use as a foliar spray for some mag. I would still order the calmag. Note you may wish to consider using GH Maxi bloom. It's a complete nutrient. It's deceptively inexpensive, and has more calcium in it than a lot of supplements! Additionally, mix fresh nutes daily, and drain to waste to help prevent the problem from getting worse, too quickly. This should help buy you time.
try amending your coco with calcium sulfate (gypsum)... It does not react to chemical fertilizer like dolomite (dolomites eleveated metals levels react to chemicals causing plant stress) I would compost the egg shells, not owning a microwave
