The goal is to have at least 5 ppms of Nitrate per dosage. So by increasing the KNO3 mixed in the 250 ml solution, we can get 1 ppm per 1 ml dosed.
KNO3
12 g for 250 ml. 5 ml of stock solution dosed is 5 ppm of N, thereby hitting the target goal.
KH2PO4
Calculations above look good. However, instead of using the full 5ml dosage, only 2-3 ml 3x a week is needed.
