Mg and/or Fe deficiencies

[AnonYMouse]

My newly imported M. ayabacana looks like its suffering a deficiency. Plant equivalent to anemia. One by one, the leaves are losing color. I think either Mg or Fe but not sure. Its not precious enough to work out something with the grower.


Has anyone experienced this?

I feed weakly weekly with 20-20-20 (0.05% Cu, 0.10% Fe, 0.05% Mn, 0.0005% Mo, 0.05% Zn). My water has
<0.04-8.2 ppm Mg. Is that sufficient (I don't want to do the math per Ray's info) for recovery? Go buy epsom salt?
