This page have pictures and yeah, I was reading about black rot- but not sure if that shows mainly on the leaves.

That looks like root rot, possibly from over fertilizing. How often do you fertilize and what strength?

Its a fungi infestation. Bring out the big guns=spray with a chemical fungicide, or if you want the gentler home remedy of soap with cinnamon extract but don't put any cinnamon powder it will desiccate the roots
