I would just let it go, the weather this year has been very unusual and has resulted in this phenomonon. I have plants that started flowering in July, my brother said that was impossible but I know what I see, they are coming along nicely now and I look forward to an early harvest as a result.

IF you get them back under more light it will take weeks to start to veg. again and by that time it will almost be time to start flowering.
