ok so for the start if this was my grow I would cut down those plants and start over with your new cfls.
the reason are:
plants look ill and very stressed! this can cause loads and loads of problems later on
plants are too fucking stretched an the stretch is huge between every node so you cant really minimize it in any way. you wont be able to get anything out of them and eventually they might even die.
you have 4 plants in one small pot this is a big NO for a grower.. 1 pot per plant!

EDIT!!!

now that i look close at the pics you can actually save your shortest plant there
just repot it into its own pot and when you do bury the stem up to the first set of leaves(it will start producing roots when its buried)
