This may not be the answer you're looking for, but my opinion is this: Because you already made the decision to harvest, you should go ahead and harvest. Maybe just harvest the top half of the plant. Put the bottom half back in the tent for another week or so and see what happens. Just one missed light cycle probably won't do too much harm this late in the game, though...in case you decide to put the whole plant back in your tent.
Whatever you decide, good luck and good growing.
