First Grow, Second Week Going into 3rd (20th Day)

Well thanks to the community here you guys gave me a lot of good advice, an at first I had 2 plants that looked like they were going to die, after doing what was said an posted they are looking great.

I now have 3 CFLs running in a Stealth Hydro Bubbleponics system, using Flora series nutes.
Needless to say I guess I'll be in this stage for awhile I'm guessing?
The vegetative growth stage, tomorrow will be another water change, an ill be using the Mac nutrients once again, but according to all the guides the long they stay in this phase is going to determine their height.

When's a good time to stop, or what will start to happen to let me know to move onto the flowering stage?
You know only lights on half the time instead of always, an what not?

I got some pics so far, I just don't feel right not doing anything I mean I haven't had to do anything in awhile an it feels weird, I'm not sure, if I could get feedback on the photos an if there looks like there are any suggestions I would love to hear them.
