Look at my grow in my signature. I started with cfls in dirt too. Use fox farms nutrients, even posted the schedule. Don't put that bat shit in your soil for the seeds, it will burn your seedlings. Neutral potting soil and water only for 2 weeks. Then you can transplant them to soil with that bat shit and start feeding. We use Fox Farms Ocean Forrest soil mixed 4:1 with perlite (for extra drainage) and some dolemite lime for pH buffering. You'll definitely need more than that one bulb for your plants. Get about 1 42 watt CFL (150 or 200 watt equivalent) per plant for happy plants. And keep your lights close 1-3" away from the leaves, to prevent stretching.

For flowering you should get one of those 150 watt HPS security lights from like home depot and re-wire it for a remote ballst. Someone posted a step by step guide i'll find it and link you. 150 watts is plenty for 4 small plants
