i think if i were you i would set the lights proper and plan on 12 hour sessions to keep the bud you have going, and chalk the others up to the learning curve

my only guess is that you are drowning the plants. back off the watering until pots are very light when you lift it and see if that helps.
bigger and more potent, i dont think so. But i think it used up the internal sugars and makes a cleaner burning smoke. just my opinion. always dark out at least 48 hours!
flowering? plants in pots - use 15-30-15 and fertilize at half strength week 2 and 5. plants in ground- 15-30-15 and fertilize once a week full strength til week 6, i believe that less fertiliser is better in the long run! cheers
