Hey there EZ, i use organics too including beneficial microbes and what i can see in your pics is the downward pointing tips on the leafs, that's an early sign of some sort of root problems. What you want to do is cleanse your soil and break down the problem roots both of which will provide nutrients to your plant through a process called chelation. So to get rid of that fuzz use something organic like enzymes or amino acids and if you want to add beneficial microbes look for bacilus subtils (BS) bacilus trychoderma (BT) , BT israelis, and mycorrhiza . Adding enzymes or another chelation to your feed will have pretty much immediate effects so do it twice in a row then once every ten days for the remainder of your grow. Hope this helps ! 🚀
