rotala macrandra japan red turning green

What's your PAR levels at substrate?

make sure it gets a lot of light and does not get shaded. otherwise you wount see red. also a lot of phosphates and iron helps

What is your kH? It has been a pain for me and the only time it flourished was when I had low kH.

I have bml and t8s. bml alone should be giving me 100 par at sub. These leaves are not at the bottom, they are in the middle to middle top. So its weird and maybe not light directed.

This one stem is not shaded, the lights turn on at noon so I will take pics. Hope that will clear things out.

Also Ive been growing these guys for many months and this does not happen much, until now.

I've been dealing with a similar issue. I noticed with I stopped dosing kno3, it started to turn green and melt away. I went 3 weeks without dosing kno3 b/c my nitrates were rather high. 2 days after dosing kno3 again, the main stems were producing off shoots and turning back to a nice red. Just food for thought. Not sure if the kno3 really had anything to do with it, but it's the only variable that I changed.

Can you provide water parameters?

I think it might be the co2. In the mornings when the light turns on my co2 is still lower than target. Maybe thats causing it?

Ill try to provide parameters later on today.
