Why are Eleocharis Parvula leaves turning white?

Hello,

Why are Eleocharis Parvula leaves turning white?

80L tank
Azoo clay based substrate
External Fluval 1000L/h
EI dosing 3 times macro 3 times micro
Pressurized CO2 system set to turn drop checker yellow since no fauna in tank
24W T5HO
Only flora is Eleocharis Parvula
50% weekly wc
Temperature is a bit on the hight side, over 30 degrees Celsius for sure

P.S: Lately I am over-dosing my EI regime to ensure that there is adequate amount of macros and micros. Furthermore, I have started using a proper pressurised CO2 kit and now my CO2 is more than enough and well stable.

Thanks

Maybe A Smart Person Can Show Up Or You Can Provide More Information

Hi,

My brain, such that it is, won’t give me anything.

The only thing I can think of is extreme iron deficiency…

Perhaps a picture and or description of how the plant got this way, did it start yellow, at the tips, did it turn white overnight?.

Hi,

A yellow colored drop checker does not indicate you have sufficient or stable co2 for your configuration.

You have a small tank and even a single T5HO can produce some good light...You may have more than you think...

Try raising the c02 and see. No harm with no fish or critters, right? Turn it way up and wait 3-5 days w/o doing anything else. The DC is just a tool, and not a very accurate one either...

Don't make assumptions about c02 based on a dc color.
