Cal/Mag deficiency reversible?

Is a cal/mag deficiency reversible? Will leaves regain proper color with correction?

Also, is it normal for new leaves to come out a lighter green and then darken up?

Cal/mag would equate to 2 different issues, calcium and magnesium. Post some pics so people can help a little better diagnose and properly help you.!
pics help out in a way words cannot

The damaged leaves won't recover. What you want to watch for is increasing damage.

As for new leaves the answer is maybe. It depends on what you're seeing.
