I have seen it discussed that Nitrate concentrations measured in tank via test kits (ie: sera) is a very different type of Nitrogen, as available to plants, than Nitrate from ferts (ie: from Kno3) because the former is from organic origin (waste).
For this Tank Journal , I get 25ppm N but I am dosing about 1/5th the nitrate of EI per the calc.
Should I ignore the measured concentrations and only focus on fert targets?
This is important because phosphate concentrations in tank are 5ppm (maybe from food?), and I feel like that needs to be less (closer to 2) or at least not increased... BUT, if I increase N for my macros without increasing phosphate then I violate the ratio 3:1:3
Perhaps I should ignore tank concentrations all together?
