My lettuce is also yellowing. I was hoping this was a nutrient thing. I
have
started feeding the fish, and also started adding Potash.

BV,

I feed my fish and also have been a religious user of potash. My water
lettuce still grew progressively yellower. I used an iron and trace element
product to no avail. My water is clear and my levels test out just fine, so
the mystery continues. I hope you can figure it out and clue ME in!
