    Sorry...I have a newbie question that I'm sure is a silly one but I am a bit confused.

    When I use the fert calculator for KNO3..... it gives an answer of how much K, N, & NO3.

    If I'm trying to figure out how much Nitrogen is in my dosage...... do I just take the amount of N in the result or do I have to add the N03 amount as well?

    For Example When I input
    20 Gallon
    DIY
    KN03
    check a solution
    1000 ml container size
    dose size of 62 ml (which I think is the same as 62 grams)
    Result of my dose
    1 ml dose

    The result shows:
    No3 = .68
    N = .15
    K = .43

    I understand that there is .43ppm of Potassium from the K in the KN03....
    I understand that the Nitrogen is .15ppm

    I am not sure whether I have to add anything in the nitirgen calculation for the NO3 result. Do I add the .68ppm to the .15ppm? Do I take 22.6% of the N03 result and add it to the N? Do I ignore the N03 number as it is already factored in the N result?

    Sorry for this...I would think I could figure it out but to me it seems like .15ppm for this much for this dosage is too low yet to me +.15+.68=.83ppm seems to high for this dosage.

    But...I am neither a chemist nor a mathematician by any means. Appreciate any help.
