....Think-- If this is your alternative Ca-Mg, it's still better than the other stuff,... I see it's formulation is still oxide based, which don't like compared to those that are carbonate based,... didn't we show you some alternative brands, like GO CaMg+, or their other hydro' version one, CaliMagic? Plenty of choices out there, but you need to read the labels to see what the sourcing is, ..I'm thinking oxides will mess with pH more than other types,...Anyway, at a value of 2, and the low N in the Bloom, you should be fine to up it to 2ml's at least,.. the dosage they give is for regular inputs, not for correcting a defc., which needs to be higher; note the % Ca/Mg on your product- 3.5% and 1.5%, which is good and comparable to others, but the label dosage seems lighter in comparison,... do you have molasses around? That will add some Ca, without the N and some Mg and K as well, plus the sugar will make the soil herd happy, and in turn, your plants happy! 1tsp/qt for a couple rounds a few days apart, plus the MagneCal,... Do me a favor, and check the pH of the wtaer you use, then the MagneCal soln. after mixing, i want to see what the oxide based stuff does to pH,... I still recommend getting a carbonate based Ca-Mg product to eliminate any N input worries,...
