Looking at several Cal-Mag amendments I have noticed that they are derived from Calcium Nitrate and Magnesium nitrate. Can you get the same benefit by using Calcium Nitrate fertilizer and Epsom salt? I have read you should not mix Calcium nitrate and Epsom salt together but can you apply them on separate days?

No problem mixing when diluted.
Same effect obtained.
More important is the ratio.
Ca,Mg and K ratios are key.
Apply too much Ca can your deficiency of other two and visa versa.

But higher concentrationswill precipitate.
Test in a clear cup first
