Use the CFL's for vegging. First 2 weeks are the most delicate. Try not to put the plants more than a few (3-5) inches for the first week. After that you can get them within the inch. And as long as it's not gonna burn the plant, the light can touch it! A fan blowing arcross the light usually helps to prevent burning.

You say the HPS is 12/12, and Flourescent is 18/6? Do you have 2 seperate grow areas focusing on vegging and flowering? If you are starting from seed, ALL the lights must be on the same light schedule. 18/6 for vegging, 12/12 for flowering.
