    Question Soil test results, too much potassium

    Greetings, so I've tested my super soil and the results came a little surprising.

    The results came in mg/kg so I put all the values to that PPM field and it seems really high in potassium (I probably used way too much compost) and sulfur (gypsum).
    So what do I do with this now? I don't know how to remove those nutrients, or should I try to add all the others to balance the ratios? The soil seemed to work fine, smell and taste are full and rich, can't complain about that.

    I was planning to topdress nutes that are missing, but it seems that there's everything that needs to be there in excess. So instead of that, just add some mulch on top and use aerated compost teas?

    I also tested my base soil, I have 100L fabric pot with 50L of supersoil on the bottom and 50L of enriched soil on top. So these are results for the top 50L.

    The nutrient levels are not so much over the recommended values, it's a little bit short of phosphorus but it's for grow phase so that should matter that much.
    There's also a problem with potassium levels, magnesium is elevated a little bit too (4% above).

    What can be done with this?

    I havent got that involved in this but i’d say the best you can do would be to ph your water to certain ranges?

    I wish i understood soil science well enough to provide an educated answer.
