limnophila hippuroides deficiency?

Why does this happen to only a few stems, while the other ones are fine?

What are your current parameter targets? Specifically curious about P and Mg, but others would be helpful too.

NO3- 10ppm
K- 10ppm + 2
PO4- 3ppm
Ca- 30ppm
Mg- 10ppm

Currently not dosing NO3/PO4 since it's over 80/10ppm

So, you dose this weekly with a 50% water change, but currently NO3 is over 80ppm and PO4 is over 10ppm?

In high tech, 10ppm NO3 may be a little low, even for soil based substrate, but accumulation would put that at 20ppm. Front loading a bit may help keep you closer to that 15-20ppm which has been pretty ideal for my skill based tanks.

Both targets for P and Mg look good to me. I asked that because the stems that have most light and probably CO2 are affected first. Might also be with cleaning tubes and filter to ensure adequate flow - could be an early warning sign.

If your NO3/PO4 is really that high, I would recommend doing a couple 50% water changes per week while still adding new ferts and keep doing that until you bring parameters in line with what you posted. When doing the WC, try to clean up some mulm
