Well, I did the water test, even though the plant was cut down about 4 days ago. No signs of the white goo of bacterial wilt, but after 4 days not sure if that would show. I did take some pics though.
The worst area of the stem is low towards the roots, a little higher up the damage doesn't look nearly as bad.
The wilting on the plant wasn't uniform all over, some stems/leaves were wilted all the way, but some didn't look too bad, in case that's a clue.
in case that code doesn't work:
