Magnesium is the element contained in Epsom Salts or Magnesium Sulphate. The element Magnesium has the symbol M.
Manganese is a separate element - symbol Mn. It is contained in Manganese Sulphate which is not widely available itself.
It is not possible therefore to correct Manganese deficiency with Magnesium Sulphate or Epsom Salts.
