Thanks so much for the advice! They are looking better now. I think I will get some CFLs. From what I read they can be pretty reliable, so it will be a good investment. As far as I can tell I should also be able to use the CFL for vegging. Bonus! Running the 600W light makes the electric meter spin round like a carnival ride...
When the plants are small ,i.e seedlings the area of the leaves is small so regardless of what light they have they still only can photosynthesise a certain amount of light so cfl's are ideal for quite awhile and if you have enough of them for the whole veg cycle.
