Does PO4 to NO3 need to be 1:4? I ask because I'm developing GSA of all things, on the glass particularly, as well as on some stone. Want to nip it in the bud.
I've heard that it's generally caused by low phosphates, and I'm already dosing EI levels. So if I want to up my phosphate do I need to simply increase the entirety of my dose, or can I throttle up on just PO4? Right now I dose these levels 3x a week:
NO3 7.45
N 1.68
PO4 1.84
P 0.6
K 5.46
This is a solution, so can I just mix more PO4 into it? Or do I simply need to up the entire does? Considering bumping it up to 2.0
How high can I safely raise PO4 as it relates to NO3?
My testing shows 1.0~ PO4 before a water change. I have not cross-referenced the test against a known standard, I just assumed the colors were relatively accurate.
