One thing is autos like long days, run lights min of 18/6 but many people do will with 24/0. Also if you are using led, consider running ambient room temps about 5-8 degrees warmer than you would with HPS (CO2 isnt a bad idea if you have it). If you arent used to starting from seeds, dont go to hot from the start. Seeds arent like clones, you cant just go balls out and hit them with strong nutes right away or youll stunt them. Once stunted, youll never catch up. You want some tips about running organic, talk to GBD. Hes got some SS mix that seems to work very well, judging by his consistently awesome plants. Consider layering the soil with hotter towards the bottom. Also dont keep the lights too close when plants are small, unless you have space restrictions, let the plants grow to the lights, Id say if you have good intensity, keep the lights at least 24 inches above the soil surface and let them grow up to the lights. Some people keep the lights even higher when starting out.
