    Question about cal,mag

    I am currently growing in a super soil. Can I use G.H cal. Mag. For supplements

    Hey Fjeff I'm not sure why you would feel you need too? Supersoils are generally so packed with minerals and organics that no supplements would be need at least until flower. I grow in a living soil which has all those but at lower NPK than supersoil.

      To answer your question directly yes you can. But a top dress of the same soil would or should supplement anything in the soil.


        If it needs it it needs it.

        I go by yellow tips on new leaves.
