    I finished my first run using maxibloom the whole run with some calmag because it is "close" to lucas. It went well but I'm going to try and imitate a jacks 321 for the next run (jacks doesn't seem readily available in Canada).

    While researching available dry fertilizers I found that the maxibloom doesn't actually hit the ppm ratios in lucas.

    Npk ppm in lucas looks like this:
    106
    46
    175

    Maxibloom ppm is:
    106
    139
    245

    Potassium is quite a bit higher and the phosphorus is significantly higher.

    Jack's 321 however looks like:
    102
    41
    171

    Which is pretty much identical to lucas.

    So my question is... Is phosphorus ratio really not that important? A 1-2 N-K ratio is the important part? Any Canadians know where to get jacks 321 or a similar 5-12-26 formula?

    Thanks

    That isn't Lucas NPK. Plus, you are over-thinking.
    Just use MaxiBloom. It is Lucas formula.

    Wasn't a fan of the lucas formula personally... too much nitrogen in flower.
