OK, now we are getting somewhere. I had a tank set up with this same substrate, Flourite Black; in my tank is looked a bit more gray than brown as it does here, but I suspect that is the light, you have a warmer white tube than I use. Flourite had very minimal benefit for my plants on its own, and I had to resort to fertilizers the same as my other plain sand and gravel tanks. And he has been using substrate tabs too, so that checks out.
Seachem's Flourish Tabs are what I use. API make one too, but from what other members here have posted they have issues so I would use the Seachem. You will also need a liquid fertilizer to provide the nutrients not taken up by roots but via the leaves. Seachem's Flourish Comprehensive Supplement is my choice, once a week and a day after the water change.
One other nutrient source is the tap water; do you know the GH? This is the major source of the hard minerals (calcium, magnesium).
