Am currently dosing my 310L Low-Tech set-up (no-CO2, muted lighting for 6 hour photoperiod, lots of floating plants, a small group of amano shrimp, no soil substrate) on a weekly basis with TNC Complete (NPK plus trace elements).
However, a month after set-up, I'm starting to see a few signs of a deficiency in my anubias - holes with a brown margin and browning tips/edges in mature leaves, small, crinkled new leaves. Nothing major as yet and no sign of algae - but it has got me thinking.
Having looked at my water report and the calculator below, I suspect that my hard tapwater contains plenty of calcium and no magnesium ions.

With this in mind, is it likely that my tank would benefit from additional Mg supplementation? TNC Complete contains:
1.5-0.5-6
1.5% N, 0.2% P, 5% K, 0.8% Mg, 0.08% Fe, 0.018% Mn, 0.002% Cu, 0.01% B, 0.01% Zn, 0.001% Mo, EDTA
Or am I approaching this from entirely the wrong angle?!
Cheers,
Ivan
