Hey

Seems my proserpinaca palustris is gettin quite yellowish at the top.
Wonder if it's because it's getting closer to light or might be lacking of iron.
Anyway to tell, other than test water for iron levels?

What ferts are you dosing?
How hard is your water? Hard water has a higher pH so if your dosing Fe EDTA the iron you dosing might not be available to the plants

@Zeus. thanks for the info.
99.9% sure it's EDTA.
Fairly hard water as ph is 8.1-8.2.
Tank a bit lower due to soil substrate.
Does it have any relevans that ph is lower due to CO2?
Micros are dosed just before lights come on and ph is 6.8.
