Fluorescent (tube) light would be preferable, but as you have the incandescent hood, try the compact fluorescent bulbs. They come in different "colours" of white, like cool white, warm white, intense white. They will give more light for less power (energy savings
) and produce less heat which is another plus over your tank. Lower wattages would work, maybe the equivalent of 25 w (not sure what this is in CF wattage) intense white. That would approach full spectrum, ideal plant light.
You've probably sufficient nutrients from the fish, although a good fertilizer like Seachem's Flourish Comprehensive plant Supplement might help, with new light. It would take very little, half a tsp treats 30 gallons only once a week (after the partial water change), so you'd be using a few drops. I would get new bulbs and see what happens. Back to the original issue, it is in my view primarily lack of adequate light that is causing the leaves to die off. Most plant authors say it is impossible to grow plants long term with incandescent light. I think this would solve the problem.
