OG KUSH 8 weeks in flower outdoors and no sign of maturity

This is crazy, 8 weeks in flower and I can see they are getting fatter daily, but no sign of maturity, Trichomes are mostly clear and most flowers are white. I have not let them get more than 24 inches tall and have pulled down taller stems and anchored them to the sides of the pot. (security is a big issue here). Any ideas when I should start to flush or stop the flowering nutes?

take a look at her at the end of October its way to early

flush now man..that thing will be done ina few weeks

thats crazy the end of august and ready to harvest. Im mostly a indoor grower but when I do do out door I let mine go tell november

I put them outdoors at the beginning of July to finish veging, and within a week I saw white flowers. Indoors OG matures in about 8 weeks, but with this outdoor grow I have learned that they can go a lot longer. Tops are getting quite heavy now and this weekend I will have to find a way to support them. I'm not complaining at all; this is quite a learning experience for me. I check trrichomes every other day for signs of ripeness, but still see clear with just a few opaque trichs.
