    The parts at page 21 and on are particularly relevant to aquatic plants.

    And old post between Paul K and myself.

    Gives some ppm's, but that's for N, not NO3.
    1/5 is still 42 N-NO3, which is 180+ ppm of NO3.

    K+ is at 235ppm for hydroponic solutions.

    Etc.............if you read that article from Hoagland, he's a smart feller, he said that there's no one single formula for all plant growth etc , long before I or Paul or other folks came out to say similar things about aquatic plant nutrients etc. Many folks get nutty ideas and take things too far and he tried to prevent that from happening.

    Some folks want to claim there is an all in one formula for everything plant.
    I do not think that myself but many folks do.
