Time to tell your buddy it's time to place your lady back into a vegetative state and try to water more and fertilize less!
7 weeks and there were still very small buds, your friend new at this? He may have just killed that plant! It's looking extra crispy but with a transplant and a couple flushes, it may just decide to live but you won't have buds anymore.
When I look closer at your pics do I see that alot of your fan leaves were spiraling which indicates a drastic heat fluctuation. Most likely it was too humid from 12 hours off and the heat built up from your lights after that time too quickly. a cold blast of A/C air in a grow room can also have this effect on leaves, usually it's not permanent though. Anyways, I disagree with the over fert in this case, you did mention using ferts though, when your friend should have started flushing weeks ago!!
