So recently my favorite plant ludwigia Japan red has been yellowing and curling not much has change with my parameter or really consumption. So I am really confused.
CO2 I try to maintain a full pH drop of 1 but sometimes it's a little heavy or slightly weaker but I try to keep an eye on it.
PH 6.6
Gh 4-5
Kh 3-4
Phos 2
Nitrate 20
I also dose iron, potassium, traces, seachem advanced.
We use mostly seachem products save for hand mixed phos, cause seachem is too diluted for my tanks.
The only real diffenece in dosing has been an increase of phos could that be it? I'm having issues. Most other plants seem fine mostly easier one but walichi is a weed, pogo Kimberly, nymphoides Taiwan, ludwigia Pantanal which has been a champ lately. So idk any help?

If I zoom in your pictures i see hair algae on your plants , which leads to co2 issue , try increase co2 a bit

I'll try to raise it up, but I think I'm already cranking it past 35 ppm I don't have a pH solenoid and this tank is in a store and the one regulator is attached to a 6 way splitter so sometimes it's a bit unstable.

I suggest using dry nutrients that you can mix yourself so you don't have to worry about them being too diluted. The reduction in red means an iron deficiency to me. Iron is what keeps the red plants red. I suggest adding ferrous gluconate as a source of iron as well as more trace nutrients in general.
