I'm still not quite sure what you are trying to accomplish - plants need three macronutrients that we can provide easily: nitrogen, phosphorus and potassium. This can generally be accomplished with two chemicals: potassium nitrate and potassium phosphate.I figured that it would cost less and have more for my money to mix up something myself then to by a small amount of prepackaged fertilizer
No, phosphoric acid will end up causing your pH to swing about wildly. As mentioned, if you want to provide phosphorus, potassium phosphate is the easiest method.will Phosphoric acid help in any way? ive been adding bonemeal for calcium and it has 10% Phosphoric acid
I'm not sure what you are using the Azomite for; are you intending to lay it below your substrate as an additional fertilizer? There are several users on these forums that have tried Azomite, perhaps you can take a look through their threads?this is a analyses of azomite is it good ? http://www.azomite.com/index.php?option=com_content&view=article&id=66&Itemid=11
Looking over some results I got from my search, it seems some (apparently incorrectly labeled) products call P2O5 "phosphoric acid" (which is incorrect).If the phosphoric acid is bad ill find a new source of calcium and stop adding bonemeal
From what I can see, it cannot be used as a water column fertilizer. According to the certificate of analysis that you linked, 65.85% of the Azomite is comprised of silicon dioxide (sand). I don't see how you would be able to get that to dissolve into water.so the azomite wont work at all for column dosing?
the member i herd about azomite form was adding 1 tbs a week as a column fertilizer
