Java fern deficiency ???

[PaulB]

Does anyone know what causes this discolourization in the tips of java fern. It is present in both new and old leaves. Is it a deficiency?

The growing areas of mine always look semi-translucent like that. I think it's normal.

i see that in the new growth, but never on old growth. I assumed it was normal too.
