Plastic is not a solid surface. It has pits and uneven areas in the surface that hold on to and trap bacteria. Eventually, no amount of scrubbing will remove the bacteria. My suggestion, get rid of the buckets, lines, hoses and start over with a fresh system. When you switched to coco/hydroton in the same buckets the environment growing the nasty bacteria is out-competed with beneficials and the water-rich environment was removed which will likely kill the bacteria in those buckets over time, and not let it set foot on your roots while coco/hydroton is in them.
