Hi again folks. I've noticed my substrate rooters slowly going transparent. They're rooted in plastic containers with Amazonia and capped with black gravel.
I'm slowly learning to troubleshoot plant deficiencies and I've arrived at either ...
CO2 deficiency which is quite unlikely since these 4 plants are spread out throughout the tank with good flow and bubble rate going into the reactor is pretty fast ...
or
Nitrogen deficiency. Dosing EI religiously.
Which of these is right or is it something else?
ps. I suspect that I have pretty soft water because GH kits don't show a change of colour. Have used JBL and Tetra. Both just showed yellowish green at the first drop and got greener and greener. Have gone as high as 24 drops but have never seen a reddish tinge before unless I'm colourblind but that makes the lady too.
