Im sorry not sorry to revive this post cause the OP already got what he was looking for but I just cant hold it anymore, as I told you guys I grow organic with AN and I was right when I said Iguana uses ph down and it doesnt have leonardite (Thats Ancient Earth, if you dont buy it you dont get any leonardite with the base nutes). Just look at the label in the backside on the bottle and it says very clear "phosphoric acid" which is the same chemical that my ph down is made of. So what I said stands true, even when growing with organic fertilizers you want to take care of your ph, when I use 4ml of iguana juice bloom per liter (the ammount it says on the label) without additives my ph goes below 6 which is not good for bloom, if according to you ph ups and down destroy the buffers in the soil, then AN is basically destroying my soil ph buffer which would explain the acidic runoff I talked about and will prove my point that even with organic, you gotta be careful. So what is it then? Didnt also kill the good bacteria? I told you it doesnt, and you guys treated me like I was ignorant. Needed to get this out of my chest, I wont argue anymore but organic = no need to check ph is not always true. And Iguana Juice stimulates the life of the substrate despite using phosphoric acid.
EDIT: Needless to say, had I followed your advice instead of what I knew, I would have burned my plants.
