Epsom salt is Magnesium sulfate. Without a soil test that determined Mg and Sulfur deficiency, it would be pure guess work to apply such a limited product and ignore the other essential plant nutrients and trace elements.
In my opinion it would be better to use a slow release complete organic fertilizer.
I don't know this company or product but I searched for South Africa and it sounds like they are in line with modern COF (complete organic fertilizer) standards.
