Hi, nice little grow you've got going. You're doing fine for a first-timer. You're receiving a lot of good advice from lots of knowledgeable, veteran growers so here's my 2 cents:
CFL lightning isn't very intense, and your stems are stretching trying to get closer to it. You're going to need a higher-powered light source, because it's not really good to keep burying the stems deeper and deeper.
Lastly, try to resist the urge to over-love them. Let them dry out fairly well between waterings. Overfeeding them with nutes can cause a myriad of issues (pH, absorbtion / lockout, leaf burn, etc) so take it easy. I usually go half-strength of what the label says to use, and since you're using Fox Farms soil which is already nutrient-rich, you should be careful.
I'm gonna follow this journey with you, can't wait to see how it turns out. I'm wishing you all the luck for some girls, and then we'll see if we can't help you get some big fat buds!
