I don't know if I should make another FIM or ...

Thank you all! I will stay with the lst for now. :)

Hey 👋 They are autos. Except for some strong genetics, the less you stress them, the bigger will be your yield. You should avoid HST as topping, fiming, schwazzing etc. as your auto has only a short time to recover. Go nice and easy, LST as much as you want, tuck biggest leaves to expose bud sites to light, but try to avoid stress that may stunt growth or cause herma. Hope it helps, good luck 🍀

With a 80x80x180 tent you should try to grow 4 plants in sog 6l pots without fiming, topping or lst flipping them early in flowering imho. I usually switch mine week 2-4 and they reach 60cm 1m20 depending strains and phenotypes. Eventually check some of my diaries if you want to see what to expect doing so. ( i have a 90x60x180 tent and grow 8 plants in sog) Grown some auto twice, they showed sign of flowering on week 3 and reached 60cm 1m10 depending phenotypes. Happy growing
