Auto-flowering strains will automatically start budding after about 2-3 weeks regardless of the light schedule they’re given.
18/6 or 20/4 light schedule is used. 18/6 is the best.
Auto-flowers have a very short vegetative period, it is only about two or thee weeks, maybe 4, and this does include the time immediately following germination, however there is not a change in the photo-period from veg to bloom, or normally this is not needed nor desired. Most people seem to agree 18/6 or 20/4 are the best photo periods for autos, start to finish, and of course some people do believe in using 24/0 with autos, but whatever light cycle you choose, most agree keeping it the same throughout every day of the entire process is best. .
You can not top or prune autos. Low stress training is the only training autos will tolerate, any stress is very likey to induce an auto to start flowering right then and there.
