Potassium deficiency?

Why did you flush if you don’t mind me asking? You shouldn’t have to flush an organic soil unless you have some big problems. If you didn’t have any issues before flushing, you’re most likely gonna have them now as flushing washes away beneficial microbes in your soil. These microbes are what breaks down the amendments and turns them into a usable nutrient for the plant. Without them, your plant will start to suffer. Also, azomite is great. I use it when amending my soil and in compost teas. It won’t really treat a deficiency but it’s great for trace minerals and as a “house” for microbes. Since you flushed the soil, I’d let it dry out completely and then give a compost tea to get those microbe populations back up. Check out www.composttealab.com for info and recipes.
