Most likely thats the problem.

How much light do you have? Since you have CO2, I'm assuming you have a fair amount of light. I'd start adding some Potassium, Nitrogen, trace nutrients (like from Tropica Plant Nutrition or Flourish), and maybe even Phosphorus.

Check out Gregwatson.com for dry fertilizers.

I have a coralight which has pretty intense rays of light so I don't think it's light.I'll pick up some fertilizers right away

ahhh i just watched that movie! good stuff...
as for the yellowing of leaves, i believe it is due to a lack of potassium.
correct me if i am wrong.
