That little soul looks like its been through the wars but there's decent new growth coming on so your doing better with it than the last guy. I agree also with Douglas1 to keep a close eye on your temps (which are fine at the moment), your watering (loads of threads here if your unsure) and if you don't already have anything to check your PH then thats your next step. If you can't afford a meter (can be bought for around 20 dollars) then an aquarium kit with drops is a decent cheaper option. The kit can at least help you keep the ingoing PH to around 6.5 but won't be accurate to measure PH of runoff water which is coloured by the soil.

Your lights are in a perfectly fine position for low wattage CFL's just make sure there's no chance of them falling onto the plant - this happens more than you'd think lol and keep them just a few inches from the plant. There's a load of CFL grows in the growlog section if you want to check out how others use them. 18 hours lights on and 6 off is great for veging plants.
Like the others said, air circulation is very important. I aim my fans at the space between the light and the plant canopy. This moves the hot air away, and gives the girls a big of a wiggle to help keep the stems sturdy.

A few other things to consider is your soil. Is it a pre-fertilized type or light nutrients, how long has the plant been in it, is it free draining etc? Don't rush to flood your plant with food either way, the last thing it needs is to be cooked with rich food. Its just something to keep in the back of your mind.
If its in fresh pre-fertilized soil it will be fine for a month or so. If in light soil start dosing, when your ready, very lightly at a quarter of whats recommended and work up slowly.

Those old fan leaves won't heal so don't worry about them now. The plant will decide whether to keep them or drop them. Please don't be chopping into it and stripping leaves at this stage, it needs as little extra stress as possible, there's been enough of that for her (hopefully its a her ).
Happy growing!
