Stem rot cause?

One of my stem plants (not sure of the variety) had new leaves coming out and generally looked good. But, about an inch from the bottom of the 6" stem a section rotted off.
When I pulled the stump out, I saw a nice healthy root system.
So, the top is good and the bottom is good and the middle rots out.
Any suggestions as to why, or how I can prevent this?

Some stem plants will rot near the substrate when they are short on nutrients or light, so the stem can float away and root in a better location. What lighting and fertilizing are you using.

Also had this happen and when the nutrients returned the root system started producing healthy plants again so don't throw them out.

I hadt his happen with some of my ludwigia. What would recommend doing? When yhe bottom of the stem rots would you just pull it up, cut the rotted part off and leave it floating until it grows new base roots (assuming there are no viable leaf node roots), or cut off rotten portion and just replant in substrate and it will develop roots on its own (assuming deficiency problem was corrected).

From memory, leaving the rotted ones still planted just melt completely and never jumped back, although the definciency probably wasnt corrected.

Using PPS-PRO and high light for 7 hrs.
The light was not very bright for a few weeks when switched over to Finnex 24/7. Have since added a second 24/7 for some decent brightness.
