I added parts of the pps-pro solution (mono potassium phosphate and potassium sulphate) along with the micro nutrients. Didn't add any nitrates cause after my WC they were already around 20ppm and I have vey hard water so magnesium was not needed. Now since it's been 4 days since adding the solutions my nitrates have dropped to 5 ppm, is this because my plants are make more use of the nitrates now that the other nutrients have been added? Can anyone explain this? I'm not complaining, lower nitrates is nice aha but just want to learn the science behind it and if anyone can recommended how much potassium nitrate to add after my next WC to try and keep the nitrates around 10-20 ppm? It's an 8g nano tank, I added about 5.5ml after my WC of each solution, should I try 5.5 ml of potassium nitrate to start and adjust accordingly?
