Well, I'm roughly at 53 lat., and I think it's the speed at which the daylight drops off here from such a long day in summer that causes problems. On June 21st we get about an 18 hour day, and I think it's the longer daytime in mid-veg that fixes them that way.
My Flos actually trigger around the 1st Sept., showing the first buds around a week after that. So eight weeks on, as advertised, they're ready. 1st Sept is about 13 hours 20 mins or so I think. But 5th November is only around 8 hours, so you would imagine they'd finish quickly, but they don't. My Grape Krush and Cocoa Kush hadn't even begun flowering last week...
