I have seen what I think is the symptom that Andy describes.  The older
leaves become noticably narrower as they age.  In extreme cases they
almost collapse all the way to the midvein.  On my plant the leaves also
became very rigid.  The narrowing was due in part to the small creases or
folds running the length of the leaves.  The leaf tissue may also have
thickened a little.

This preceded and accompanied a few other symptoms that I've posted about
here before. I haven't seen the older leaves shrink like that since I
started circulating water in the substrate.
