Ok, your plants are acutally looking pretty good dude. They are going to quickly OVERGROW your space though and your light is basically just enough to keep them growing decent at this point. You need to buy some "Y" socket splitters and double up on the bulbs. If you goto home depot they have a full spectrum 100 watt equivelant CFL by the other regular ones that has a pretty box, that's the one you want for right now. As far as nutes go, make sure that you only use the FF nutes at like 1/4 strength to begin with..strong stuff and the label directions are almost always too strong even for plants under HPS when they are small and in soil. Being under CFL you need to keep them as short and bushy as humanly possible so at the 4th or 5th set of leaves you need to immediately clip off or "top" the upper growth tip..just snip it right of or pinch and twist gently being careful not to damage the little side shoots that will grow in and replace the original top growth shoot. This will make your plants wider and bushier as opposed to tall and side branches will grow in quite quickly once topped as the plant sends hormonal signals to the lower branch shoots that it's time to fully grow out because it thinks it's been attacked or eaten at the top by a predator, etc. Double up on that light, make sure your temps are no more than 85F max and you should be good...then as soon as they grow in the new top shoots and look like a "Y" at the top and side branches come in and it starts growing really vigorously then it's time to set the cycle to 12/12 and flower.
