Great help my friends. I also suspected a clumping of the nutrients. I also noticed that there were fewer air bubbles in this tank. This made it easier for the nutrients to clump together. So I increased the air supply to that one hose to blow the roots clean. The result was already visible after a few hours, see last photos. Thank you very much for your help.
