Thanks for the help as always Weedhound. I honestly think that I have what I need down. Last flower, it was a matter of not enough room for the roots which led to the switch to DWC, then I just didn't have enough air/air stones.

This time, I think the diffuser tubes didn't cover enough area and there were some dead spots where the roots chose to hang out. That is why I decided to put them in individual buckets. They seem to like it a lot better in there because there's nowhere that the air doesn't hit so the roots cnt float into a dead spot.

I will check to see if my local shop has that excelurator stuff. How long do you think I should wait to introduce nutes again and should I get rid of the rotted roots or just leave them be?

I think my problems are just a matter of not enough air. I am using hygrozyme because they don't have cannazyme where I am. I looked into the Voodoo juice that rhizome told me about but the stuff is like $200! I used a new bin and new everything this time so I don't think anything is contaminated. I think it was just not enough air, but now I am left wondering what to do next to save my young ladies if possible. If I can't save them or if you think it wouldn't be worth it, I am just going to flower my 4' tall x 2' wide mother plant that has been growing for about 3.5 months now!
