Your sig says there's a Kind soil mix in the bottom of some of the containers, is that accurate? If so, you aren't really following their recommendations... "DO NOT ADD ANYTHING other than carbon filtered water to your grow", is what they recommend. As for base media, they recommend potting soil, not the mainly peat mix you're using. I've never used Kind products, but the recipe looks familiar enough...it's a very hot supper soil.The manufacturer has pretty strict instructions regarding pH adjustment and use of amendments.
If you're having troubles, you might want to send them an Email and get their input to resolve them. They know their product better than us web crawlers.
