I would not consider Wisteria
low light; it needs moderate to bright. Anacharis
is probably similar, some sources say "low" and other "bright" so take your pick. Hornwort
tends to fall apart for many regardless of conditions. Java Moss
will thrive in any light once it is established, but it does not appreciate changes.
But your light may be perfectly adequate, and i can easily assist here once I know whether you have a fluorescent (tube) or incandescent (screw-in) fixture.
Now to the nutrients. Depending upon the plants and the fish and your source water's hardness, all nutrients can occur from fish food and water changes. If supplementation is necessary, then Flourish Comprehensive Supplement will probably be sufficient.
Excel is a carbon supplement and i do not recommend it; there is usually sufficient CO2 from fish and bacteria to enable most plants to grow, and adding carbon via Excel is raising the balance of light and the other nutrients. Trace Elements are sometimes beneficial, again depending what is in your tap water and the fish food. I only use Flourish Comprehensive, and have for 3 years, and this with my very soft mineral-less water.
