It would also kill me to cut off the five inflos, but be assured that those are draining the life out of your cutting. The inflo will not regrow but your plant will likely branch below the inflo, so you have more chances of blooms next time around.
Cut the inflo off about an inch above where they start; the remaining nub will fall off by itself.
I would soak the entire cutting in a tub of water for 24 hour; that will rehydrate it a bit.
Good luck. Oh and yes, a grow light will be good considering we are entering fall and shorter days.
