Air stones

I am week 5 of a AG grow. I have 4 plants, 1 is about 6" tall and the balance 3 - 4". I am running 6 (42w) cfl's in addition to the AG deluxe lights.
I am running a air pump rated 60 gal. I have a 7" air stone across the front of the AG. I also have two 2" stones, one each along each side. I put the 2 " stones in place of two 3" round air disks/stones. Since then my plants seem to droop.

Has anyone ever noticed a diffeernce in the amount of air put out between the cylinder stones and the air disks?
Could the plant droop be from poor air circulation in the tank?
