Try calcium and K the atomic mass of Ca and K are very close and you can knock off K on the soil particles with the use of calcium. There was a grower I meet from the thumb in Michigan when he bought a farm he would spread 1 ton of gypsum and 1 ton of high calcium lime. after that first year, it was 1,000 pounds of each gypsum and calcium. beans on beans for 15 plus year and beating the county T yields by 20 plus BPA. he foliar every week with several different materials but low-cost operation and made money. The time I spoke to him he was planting all Non-GMO with a $2.00 premium. and all no-till so the equipment cost was pretty low.
He didn't put up his soil test info. Seeing as the man is from Kentucky it's easy to assume he has acid soil but I wouldn't recommend adding calcium just by guessing he needs it.
