Think you ended up alright if the kit has the OG at 1.088 and you hit 1.090, close enough for hand grenades and brewing !
I do believe that Northern and Midwest are under the same corporate umbrella.

I'm at day 3 on this brew. Room temp in my basement is at 70 deg. fermenting temp in the big mouth is 77 deg. There is a storm going on in there. I have no problem with these temps with that yeast, I started at 68 and will let it go where ever, but I think in another day or two it will start dropping back down. I would like to secondary this coming weekend but will have to see where it is at.

Mine was fully fermented out at around 10 days hitting around 78 degrees during the free rise. That yeast is a monster.
