Definitely over-fertilized.
At that stage of budding I would quit fertilizing all together.
Not being a smart-ass, but seriously, why do you think the plant at that stage needs fertilizing? Do you think it's gonna make the buds fatter and/or denser? It won't.
I am prejudice against fertilizing at ANY time but, really, fertilizing beyond the veg cycle is just asking for the kind of trouble/worry you have at the moment.
If it were me, I would leave the plant alone unless your soil is dry. Flushing it may produce symptoms of over-watering and that, ontop of your curling, would send you into a tailspin of panic...Just wait until you think it needs a drink and then give it only water and no more fertz (and no molasses, either).
Other than that, it looks like a nice bud.
Wishing you the best of luck!
