20hr light to 12/12

So in the end, due to how long it will take the gorilla glue to fully flower as shes photoperiod, I have taken her outside and we'll see how she far she goes, not the best and I don't think she'll even make a harvest in time but I just didn't plan for an auto grow to last as long as that will last in the tent D

When the plant is getting less light each day, it “thinks” winter is coming. This is why giving a plant 12 hours of darkness a day causes it to start flowering. However, some strains (especially sativas and hazes) tend to take a long time to finish maturing. In this situation, shortening the day period will help plants mature faster. For example you could try switching to a 10-14 schedule (10 hours light, 14 hours of complete darkness) or even 8-16. If you have an auto-flowering strain that is not maturing, try switching from the standard 18-6 schedule to a 12-12 schedule just like for photoperiod cannabis plants. The longer nights can help encourage plants to finish flowering sooner if you have one that’s taking too long. Important Note: Reducing light hours means lower yields. Switching from 12/12 to 14/10 shouldn’t make a significant change, but it’s still something to consider when you’re making that decision.

Personally, I'd wait that extra week, before switching to 12/12.. The others won't exactly grow much bigger, but you'll probably lose out on trichomes and strength.
