Have you switched lighting recently? I seem to remember my java went through this sort of thing when I increased the lighting. It eventually returned to it's dark color.

Are the leaves soft or leathery? If they are soft you may have a nutrient deficiency happening.

I agree, but as long the the rhizome stays firm, you should get new growth.

Thanks, Kara

I will have to check the leaves I guess, next PWC. The light has been on the java fern for about a month or so now.

When I first got my new light I moved it from my low light 50 to my 20. It was in bad shape. I have gold barbs that have been munching on it. But after about 3 weeks in the 20 with more light and no grazing fish, it started showing a lot of new growth. But now some discoloration is happening and I was concerned about a nutrient deficiency since I have more plants now that I'm feeding.

Are those black spots actually fuzzy patches of something growing out from the leaf or flat spots against/on/part of the surface of the leaf? It kind of looks to me like those are patches of black/gray "fuzz" growing out and away from the leaf. If so, then it's probably some sort of algae ~ probably black brush algae (bba), staghorn or something like that.

How many watts do I need to make my swimming pool a high light tank?
