Soil Test... post harvest

I had noticed a Ca deficiency in many of my OD plants this year, so after harvest I sent a soil sample in to the University of Missouri for analysis. The test pointed out not a Ca deficiency, even though I had plenty of Ca in the media. But a  K toxicity, that was not only locking out Ca, but the micronutrients as well. The first two numbers listed on the results after the nutrient are the averages, and the last number is my soils number. K was 420ppm almost 200 ppm's above average!!   Morale of the story, be careful with bloom boosters ! Peace
