Seed banks list autos in two different ways, either as total days from seed or as weeks of flowering only, and mixing them up leads to harvesting far too early. A strain marked eight weeks flowering is really an eleven or twelve week plant once you add the vegetative stretch. The listings on https://turboautoflowerseeds.com convert everything to days from germination, which removes the guesswork when planning a tent rotation. Add a week or two on top of that for slower phenotypes anyway.
