Hi, my plants have some Nitrogen deficiencies and I bought a bottle of Canna Mono Nitrogen. The bottle states: Contains 27% N. (Contains: ammonium 6%, amid nitrogen 11% and nitrate 10%). Use 1-2ml/l. I used 0.5ml/l and my EC rose from 1.2 to 1.6. As it was a bit high for my taste I diluted the solution immediately with fresh RO water to EC 1.3. How much Nitrogen are you using if you experience Nitrogen deficiencies? I can also work with EC values if you can state any. I hope you can help me out.
