m0useanswered grow question 3 years ago You wont stress it out to much. Photoperoids will not show signs of flower till after a week and a bit after flip. It will show sex but not make true flowers.
All autos can be run start to finish on 18/6 some do 20/4 or even 24/0 but plants still need rest.
If it purchased the seeds as an Auto then it is most likely an auto and you should switch the lights back.
If its a photoperiod, it will grow single blade leaves as it reveges and then can be switched back into flower if needed.
A lot of newer autos are vegging just as long as a photoperoid plant.
Good Luck!
