    Hi all,

    I ran some calculation on the seachem flourish nitrogen fertiliser as it is difficult to access KNO3 directly in Hong Kong and I probably need to use the seachem flourish as my primary N source.

    I know the product is mainly for nitrogen increase but there are presence of potassium in it. I don't quite understand the increase in Potassium and Potash as calculated

    I understand that the NPK ratio in seachem nitrogen is 1-0-2, which is expressed as N-P2O5-K2O

    I also looked up a little "fact sheet" as provided, which kind of confirmed that the K ratio in NPK is expressed in K2O

    Do I understand it correctly that since K is expressed as K2O, a 1mg of Nitrogen introduced will also increase K2O by 2mg, and K+ by 2 x (39x2) / (39x2+16) = 1.659mg?

    It appears that from the calculator the Nitrogen to K2O ratio is not 1:2 as suggested in the analysis above?

    Perhaps (very likely) i missed something from the analysis above, appreciate your time in reading and answering this!
