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.

What kind of/size container are they in?

Are you planning on growing them the entire time in that medium or are you transferring to soil?

What kind of (if any) nutrients are you using?

6 inch pots, they are already in soil im not using any nuts at this point

Well, when it comes to CFL's, more is always better. How far are the bulbs? CFL's should be less than six inches away from the foliage.

How are the roots doing after the transplant?

If you have a hydroponic store near you, I would suggest picking up a veg and bloom nutrient. You can get a decent setup for $30. It will pay off in your final product. If not, check out home depot and pick up some Superthrive from the garden section. Roots go nuts on the stuff, and I've found it is a great booster when used right after a pot transplant, and for general watering for root strength.
