In the case of calcium, transport from roots is usually a bit limited, so for supplemental calcium applications, foliar applications may be the best method
I think my findings were around 250 ppm.
I can not remember where that number comes from originally.
Probably comes from something similar to what @Northern_Loki posted.
Between 200-300 ppm or 0.2-0.3 grams per liter AKA 2-3mg per liter.

I think what he is not saying here is a calcium complex via amino acids.
So I think something like Albion Metasolate Calcium comes to mind.
Which is way better to use, in my opinion.
Anyone know the particle size of Ca Acetate?
I am remembering something about the particle size being to big to enter the plant through the leaves.
It is true there are better choices for getting calcium into the plant via foliar spray.
I think my notes state to use Ca Acetate via drench not spray, but I would need to check to be sure.
