Oyster shell takes quite a while to break down. If you are looking for more immediate cal mag I would do an egg shell vinegar mix and make some organic clay mag that way.
 
I’d be more inclined to add a small pinch of the oyster shell along with half a handful of good quality neem and kelp meal with your castings.
If you can get hold of malted barley that’s fantastic too.

Good luck
