I have the same "problem" with small-leaf java fern. Don't know if
it's really a problem, because there's no other signs of deficiency
and it grows well. Anyway, this is probably some kind of deficiency,
can't think of anything else..
PMDD and CO2 here as well, NO3 6-10ppm, PO4 0,2ppm, traces, 1,8WPG.
Sure not snails.
