If it is in a pot, you can bring it indoors and put it on 24/0 and dose it with superthrive at 2-4 drops per gallon, ONCE. Give it BLUE flourescent or halide light, and leave as many LEAVES as possible. If there are any seeds, remove them.

Good luck, and if you get her to re-veg, take cuttings ASAP to regenerate her- a big revegged mother in old dirt can be a crotchety wench.
