Notes:
There are still black patches on the java fern leaves. You can see them in the photo on the center leaves. I don’t know exactly which nutrient deficiency its showing, but the Rotala plants are also still showing some transparent spots in the leaves. I don’t know if its just my imagination, but the Rotala indica seems much greener and better today. Perhaps that extra dose of nitrates/phosphates is what it needed. Perhaps the java ferns have the same nitrogen deficiency.

The stargrass, though, is still showing some pale leaves, that is still probably an iron deficiency. Will continue to keep the levels at over 5 ppm nitrates and 0.5 ppm phosphates to see the changes.
