The new leaves of my A. lanceolata once exhibited similar symptoms. The
effects were very pronounced, but did not seem to affect the A. bartieri
v. nana. It may have been calcium or boron deficiency -I hadn't made a
water change in many weeks. The light intensity was high. The GH and KH
levels in the tapwater were similar to those in your tank. Transferred
to emersed conditons with a proper nutrient solution, the new leaf growth
is normal.
