IMHO...... Marijuana likes to dry out between watering, you may be keeping things a little damp.
Indeed, the strongest of the plants will choke out the weaker, but in the end they will also suffer from being so crowded.
As the plants that survive get older, they will eventually start pushing the dirt out of the container with their roots. You will end up having to water every day as the plants won't be able to retain moisture.
Using Day-light CFL bulbs, if kept close enough to the plants can get you through veg, but I suggest switching to bud while they are still small...for a better survival rate overall (less root space required). Normally, I would say a gallon of pot for every foot of plant in height...so you see that there will be a space struggle.
Softer white CFL bulbs for blooming, seedlings have to be at least two weeks old. You should use some type of timer...and you will have to make sure that their 12 hour dark time is pitch black without interruption.
Food will be important, but you will have to be careful not to burn the roots as they eventually will be about all that you are watering.
A CFL grow, under the best conditions is not ideal...I truly don't think you will yield very much at all. But like the rest....I wish you luck.
btw. There is nothing that I have mentioned that you couldn't have figured out on your own doing all the research you say you are.
