Recently I've noticed the plants in my mid light EI 20g high tank are lacking something, and given that the tank reads 3ppm PO4 and 30ppm NO3 right before the 50% water change I'm guessing it must be a micro of some kind.
I did a bit of research but cant pin it down to a specific element. Anyway, it got me thinking about calcium so I tested the water and it came out at 4dGH, very soft. Could a GH as low as this cause a calcium deficiency? I've never really come across calcium before, I guess as its in the water its never really a problem.
FYI in case you are interested, symptoms include misshapen leaves, stems going brown and breaking off half way, and lastly, the leaves loose all their green colour between the veins, get a good look at the vein structure but thats not quite the point I dont think!
I'm using the AE trace which I note doesn't contain calcium or magnesium.
Cheers all
