New pictures incoming. Here's before the replanting:
Some of the l. inclinata cuba showing leaves curled under:
Blyxa cluster with a red minor tetra photobombing it:
I'm still futzing around with camera settings, can't seem to get the pictures to come out as bright as I'd like and not look washed out.
Drop checker is showing sufficient CO2 now. Adjusted the outflow direction (spraybar is next weekend's project) and it solved a lot. KH and GH are both very high, going to try cutting with RO/Distilled water tomorrow on the water change. I think the hardness is what is causing some issues with the ludwigia being stunted and curled.
