too much light

are these Frogbits getting too much light, or something else is "burning" them

Looks more like potassium deficiency than photoburn.

Note that all the affected leaves seem to be older ones.

Yeah that looks like potassium deficiency. Do you use fertilizer? Something like Leaf Zone or Fourish Potassium should help.

Not too much light.
Mine (frogbits) are growing in a greenhouse, with MUCH brighter light than any aquarium. They grow larger, and are strong enough to support some emersed leaves.

yep I've got Flourish Potassium. I'll get right on that, thanks!

I had removed a lot of my plants, so I also backed off on my fert schedule. I guess too far.

I have a Java Fern that looks similar, maybe potassium deficiency too?

and then at the base (about the bottom 2inches) of my Hornswort it is looking rather brownish and stiff, not soft and green. The arms are still soft and green.
