From germination to final pot will get you the best results, if you do decide to transplant, be fragile, water with a root stimulator after ttransplanting and have it in your final pot by about day ten, before 2 weeks. From there just let it grow, I give mine 19 hours light / 5 hours dark (18 hours light is considered the mínimum if you want a decent yield, outdoors would require a mínimum of 6 hours direct sun light and mínimum of 12 hour days) I reccomend HPS mixed sectrum bulbs for the full life of Autos - as from 400w. Fertwise it would really depend on the soil you decide to use.... Heavy Mix soils with nutrients for both veg and flowering + adding some natural bud sweetening sugars after about week 5 until the last 10 days before harvest. Then for the last 10 days I water with distilled water.
