Plant deficiency

[boyen]

Hi Guys,

Any ideas wha could be causing some of the leaves on my sword to look like this?

I dose with macro and micro daily and use root tabs for my bottom feeders.

Parameters:
50% water change every week
Temp: 79F / 26C
PH: 6.75
CO2 pressurized injection: 25-30 ppm
NH4: 0 ppm
NO2: 0 ppm
NO3: 5-10 ppm
PO4: 3 ppm
Fe: 0.1 ppm
K: 20 ppm
KH: 6 dKH
GH: 8 dGH

NO3 and Fe is on the low side, I guess?

Thanks!

Do you have a pic of the whole plant? That leaf looks like emmersed growth.... So it will die back regardless.

Thanks!

The plant is fully submersed. The leaf has been like that for a while and doesn’t look to be dying. All new leaves have a reddish look but normally turn green when fully developed.

Full picture attached. It’s a large plant so a little difficult to get a good picture.

Just trim off the bad looking leaf, likely a macro deficiency. How often do you use tabs?

I use tabs approx. every 4-6 months.
