I recently pulled out and pitched a 13-year old stand of A. barteri nana
that fit that description pretty well.  It was in a low-light tank that I
maintain mostly for keeping botias that habitually tear up more delicate
plants.  I tested the tank water a few days ago when this thread started
and found 30 mg/l of nitrate.

It appears to me that this sort of stunted growth can't be diagnostic of
nitrogen deficiency.
