my first grow

I started my first grow and waz looking for any sugestions or tips to better my plants. the seeds i have are called big bertha, when i germinated the seeds everything seemed to be going good, 5 out of 8 cracked and grew their root. i planted them in coco natural plant medium. they took 3 days to sprout out of the soil, i waterd them every 3 or 4th day. for the first 2 weeks they were growing fine. its been 1 week and i havent seen any change in my plants, its like they stoped growing, any sugestions??
im using 4 200 watt 3000 lumens cool white cfl's.

im far from an expert but I think you want daylight spectrum bulbs for vegging.. the cool white is better for the flowering stage its in the 2700 range .. the daylight is 6500ish.

would cool white blulbs slow down the growth process? and also what about the warm white bulbs?
