Spent the week rinsing and massaging roots, cleaning, filling then re-cleaning and refilling reservoirs. The rot is gone. Replaced with beneficial microbes from Advanced Nutrients Tarantula, that I made into a tea. This tea has cured the rot and also made a huge contribution to the roots and therefore, the whole plant.
Am very impressed with the plants progress, vigour, vitality and strength!
Now that the crisis is over, I'll be using the tea twice weekly to replenish the ranks.
