How long has the tank been set up? What is your calcium level?
It takes months for it to develop and spread.

it's been up for about for a year and the CA is above 500ppm

The only thing I can think of then is lighting. Maybe your current lighting is not enough for it to grow. Coraline needs 3 thing; good circulation, high Ca, and good lighting.

should i let my light stay on longer then 6 hours

It wouldn't hurt to keep them on about 8 hours, although longer photoperiod is not a substitute for poor lighting, not saying there is anything wrong with your PCs. What do you do to maintain your Ca levels?? Do you have rock with coraline on it to seed the rest of the tank?

i put raises calcium by seachem two times a week i just got a calcium test kit about a week ago and it was the first time that i look at my CA levelsand i did not know that they were as high as they are.

I don't think lighting actually is a major concern for coraline(my fish only has 70 watts of NO lighting and coraline is spreading like crazy)....they keys I believe are ....
A quality source of coraline(LR)
A stable/mature system
Consistant levels of calcium/alkalinity/ph
Circulation
Patience
I know it doesn't help you much but I have sheets of coraline falling off the walls of my rubber maid refugiums...sometimes I'll crumble them up and let them distribute thru the system to increase growth....even gave a bunch away to a fellow local reefer.

Your calcium IMO is a little high for the fish. 400-450max ppm. Higher calcium stresses them out. For coraline algae, you need a good balance of calcium,alkalinity,PH and proper lighting. I had all of the rest and added proper lighting for an explosion of coraline. Also low phosphates are important.
