Calcium nitrate is a nitrogen fertilizer that can also be used to give plants calcium.
I've read that you shouldn't combine calcium nitrate with sulfates and certain kinds of phosphorus (I believe this is because the combination may make certain of the nutrients so they don't absorb how they should or something).
My question is, if I have such as potassium sulfate and/or magnesium sulfate in my soil, could I get around the problem by spraying calcium nitrate on the leaves instead of adding it to the soil where the sulfates are? Would the plant absorb them all just fine, in this case?
This question is for plants in containers. If the kind of plant matters, this is for peppers, tomatoes and such.
