I did not, I used organic slow release dry amendments, its a local brand, there aren't a lot of options available where I live. The components of the amendment are 5-7% N, 3-5% P2O5, 3-5% K2O, 3% Ca and 0.5-1% Mg.
Maybe I should mix another amendment that only has Magnesium? What % of Magnesium should it have? Thank you so much!
