I'm pretty sure my roots are rotting big time. I have been scooping insane amounts of slime out of the res, and when I do, the pH goes up. The air stones are also getting completely clogged with slime, which I am sure furthers the root rot. I am glad I am only a week away from harvest so I can have some time to rethink this DWC set up and get some air stones in there that will stay put and provide enough air for my roots.
