why is my Samolus Parviflorus doing bad?

I've got a Samolus Parviflorus which was doing really well about a month
ago.. I have since switched using co2 tabs and gone with a 10lbs bottle with
the whole setup. (overkill, i know) Since then, it has been developing
light algae.
ph - 7
all other levels are normal using the test kit
light - 35watt Flora-Glo
fertilizer - 15ml Tropica Master Grow once a week after a 1/4-1/2 water
change.
At the same time I add 1 ml of liquid Fe and continue every other day for 3
days, so 3 ml total for the week.
I add 1ml of Potassium twice a week
- The lights are on for exactly 12 hours/day
- The tank is partially full with 7 swords, 1 anubias barteri on wood, 1
Samolus Parviflorus, and a 1 fast growing hygrophila corymbosa which is
totally green and no algae..
- I've got about 9 neon tetra's, 4 angels, and 1 strawberry tetra. had an
SAE, but died (old age)
- Aquaclear 200 filter with carbon, ammonia, sponge..

any suggestions?

I was thinking of picking up "the beast" from AHSupply, 96 watt 6500k to
replace the lighting, but I'd like to find out what's going on first with
this plant before i go ahead with it..

is the Samolus Parviflorus considered a fast growing plant? I'm wondering
if i should pickup a few more hygrophila corymbosa's?? maybe they might
take the algae away before it can develop?

No, Samolus parviflorus is actually very slow growing. It needs plenty
of light and moderately hard water. Its native to the east coast of
the USA. It goes by the common names of Water cabbage, Water
pimpernel, and Water rose. It will send up a center stalk bearing
plantlets and will flower when it breaks the water surface. It grows
much faster emersed as a bog plant/edge plant in ponds.
