I had my container soil mix tested, the base saturation percentage is Ca 54%, mg 21%, k 10%, na 4.5 %. Ph 6.7, tcec 7. I added 1cup (for 65 gal ) of gypsum to raise cal and lower mg. I believe this will also lower some micronutrients, igot buildasoil big 6, but haven't added any. I waited a few days, then flushed pretty good. My micronutrients are b .87 ppm, fe 120 ppm, mn 20 ppm, cu .55 ppm, an 2.82 ppm. If anyone can help, thank you
Also I believe it will also raise my sulfur, which is 86 ppm. But my understanding is that sulfur will reach out.
