DJ Short has two strains of Blueberry. True Blueberry is an indoor only strain and I have never tried that outside. I beleive that chain has not been broken and if anybody knows for a fact it was, don't tell me. I don't want to know!

The "newer" indoor/outdoor strain was made from European stock and is very similar to the PeekseedBC version, which I have't personally raised. But I have tried it and it was pretty good but I didn't have the utmost regard for that grower, so take that for what it's worth.
You live in the USDA hardiness zone of 5 or 6 but local conditions around the Great Lakes can vary widely, as you surely are aware. Forty or 50 miles one way or the other you can make a huge difference. September and October rainfalls on the eastern ends of lakes Michigan, Erie and Ontario can raise havoc with fall harvests but their warming effect can also work in your favor. It's Mother Nature.
The nice thing about Flo is that if you get a mild fall, you can have a new harvest every 10 days to two weeks starting the last two weeks of September, give or take a week. This can last until early November if the weather holds. Having a secure grow is paramount because if you have to chop it in September you can miss out on quite a bit of production.
Don't put anything in the ground until soil temps get warm or things will just sit there until they do. Good luck!
