I was somehow able to fight the rot off with H2O2 and bennies and save one of the plants. New roots coming and some progress can be seen. So far very resistant to my mistakes.
I will take pics with the lights out at some point and if someone wants to see the roots I'll try and take pics of those too. I only have my phone camera so unfortunately the pictures won't be high quality, sorry for that!
17th day. I cut off 2 of the lowest branches and did the latest cleaning of roots with water only as I changed the water in the reservoir.
Special thanks to my wife. She's my muse and I would not be able to do this without her support (she insisted me to keep on going even though I had already given up on this). I love her so very much! :)
