Small critik. It appears your growing style is still wanting to hold on to salt growing techniques. Lock outs, and toxicity should not even be on the radar with living soil growing. It is more simple and easy going. With natural earth, the changes dont happen as fast as salt growing. When you mess up, it gives you more time to fix. No immediate uptake of most inputs. As long as your soil is getting fed diverse compost items, it balances itself out. No omg, now what? And your worms will love it when you feed them. They devour watermelon. Bury couple pieces, no rind, and see what happens. And p.s. worms give you back whatever you feed them. I would step back, take a puff, and try not to give them too much bottled inputs. P.s.s. your plants look good tho. Nothing looks bad. So take it or leave it, you still got a nice plant that looks happy.
