Or excess nitrate?

But now i've noticed my Anubias (barteri var. caladiifolia "1705") seems
to
have the similar problem in its NEW leaf. The old leaves are still find
but
the new leaf that has grown seems lighter in colour with a hole that is
developing. My java ferns in my tank are doing very well though (new
nodes
keep appearing at the ends of the leaves for propogation). Any ideas??

It's natural for new leaves to be lighter in color.

As for the holes...my guess would be something is eating the leaves. It
could
be a deficiency, but given your low light levels, I think a salad-loving
fish
is more likely.

Though some people claim that fish don't eat anubias, IME, that's not
true. My
clown loaches routinely chewed holes in my anubias leaves, until I moved
them
to another tank.

If you can take a photo of the damaged leaf, that might help the
diagnosis.
