The discussion seemed to change to lights and that may not even be a factor here.How long did they veg for in 5 gallon pots? They may have needed more time.They may need 4-6 more weeks of flowering that happens sometimes especially with a lot of training, you can slow them down if to much is done after they start to flower.keep an eye on the trichomes and let them go until they want to.They may still turn out good.Pictures look like they got flipped to early though.Like kinggrow1 said earlier 9 weeks on a 6-7 week advertised plant and if flipped early add another week.I have had the same strain next to each other same everything and there be a week difference in maturity. Some are just immature like me.Hope they turn out just fine for you.patience is the key factor. when veging we want to get to flower,when flowering we want to get to harvest its not fast food.A good home cooked meal is always better than fast food its worth the wait.
