Nitrogen deficiency - how much Nitrogen do I have to add?

  1. 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.
