Hey there everyone, I am a new grower am on my first grow, they are about 6 weeks old.i have them under a 3 bulb fluorescent light, which is about 6 inches or so above the plants. My question is is this a good height or should the raise the light higher, to me they look smaller then some of the pics I have seen of younger plants....thanks for any info I can get...

Normally you want at least 100 watts for each plant. You're gonna need to get a bunch more lights.
I agree with Peyton.
It looks like you have about 15 square feet of grow area.
Right now you have roughly 16 watts per plant.
And 6.4 watts per square foot.
You can use CFL bulbs for brighter focused lighting. More fluorescent tubes on the back and sides of your plants will help a lot also.
Keep in mind when the plant goes into flower, it will help your yield if you add additional wattage per plant.

100 watt CFL or 100 watt equivalent?

Never use the equivalent number. That number is only used as a guide for people to replace their incandescent bulbs with a CFL bulb of similar brightness.
Incandescent bulbs cannot effectively grow Cannabis, thus, that number is useless. Only discuss CFL bulbs in their true actual wattage.
Yes they make 100w CFLs, but it requires a special fixture.

Ok cool, thanks for the info. So if I can figure out how I can use
4 - 23 watt equivalent CFLs per plant....will be moving them into
Grow box as soon as I finish building it...6x4x2

4 is a good number to start with for Veg. 23 watt bulbs are good for the lower power, and ability to move the lights around to give the plants a nice coverage in light.
When you flower, I would suggest adding 2 more bulbs per plant, but it's not required to grow them through flower. The extra light is helpful though.

I have 2 x 300w [actual wattage] CFLs that I don't use, so, yes, you can get 100w and beyond cfls
