Nalani,

"I have a setup of two lights that equal 200 watts, 3200 lumens and each color temp is 2650k."

That color temperature is too low for effective plant growth. Seedlings like lots of blue light and will preferentially grow toward a cool white fluorescent bulb and away from a warm white fluorescent bulb (which actually has a cooler color temperature than your lights). Not to be disparaging, but in my opinion your lights are closer to heat lamps than they are to grow lights.

I'm going to disagree with you again, Maine. I have what appear to be 42W warm white bulbs as temporary lighting. All of my plants insist on growing towards, not away from, the light source.

Warm white bulbs will work just fine. If cool white or daylight spectra bulbs are offered, purchase those instead.

Sam,

"I have what appear to be 42W warm white bulbs as temporary lighting. All of my plants insist on growing towards, not away from, the light source."

I think you misunderstand what I said. What I have observed, and what several other people in this forum have also reported, is that when you have both cool white bulbs and warm white bulbs present, the plants grow toward the cool white bulbs in preference to the warm white bulbs. I have no doubt that your plants would grow toward your warm white bulbs in preference to no light at all. It would be rather odd if plants grew away from the light.

But, given a choice, plants will grow toward the cool white. So, since I can get cool white T8 Philips 48" bulbs from Home Depot for $2 each, its a lot cheaper for me to give the plants what they want anyway.
