Rotten roots

Hi @HDROBEAT I had a similar problem in the first month and a half of this season. I've cleaned the reservoirs every few days with no effect. Then it hit me. Because I was only cleaning it "organically" with only water and a sponge, a lot of bacteria were still there after cleaning. That's why I decided to clean it with a hospital grade chemicals and it did the job. The moment I've cleaned it, all 4 of my plants started to regenerate. All my plants were stuned for over a month in this early stage because all the roots got just after a day after every res change slimy. I took a syringe and tried to put a precise stream of water on the parts of roots that were slimy and I managed to get rid of it but it eventually got slimy again after a day or two. The conclusion: Do a water res change, clean your res with chemicals and try to get rid of the slime with a syringe or a stream of water but don't touch them with your fingers! They are very fragile. Eventually you get rid of it. And try to keep your water cool.
