Auto flowers and photoperiods react differently- which is why you are probably hearing two different things.
Autos donβt handle stress well, it stunts them and keeps your harvests small. LST is the only thing Iβd recommend
Photos one the other had are in the vegetative state longer, and can therefor handle and recover better from the stresses of topping, fimβing and the like.
Hope this helps. Happy Growing π±
