Srikanth,
Good point. Calcium has to be supplemented via calcium nitrate. Since the mix I suggest is cocopeat+vermicompost(50:50), there is some amount nutrients present in that. That takes care of magnesium and calcium.Again depends on the source of the compost.
An external source of magnesium and calcium is needed if the medium is straight cocopeat.
Some NPK fertilizers contain Mg in the form of MgO though.
