I brewed a triple about 4 weeks ago, OG was 1.090. i was told to just pitch two vials rather than making a starter. I soon realized that my 6gallon bucket was nowhere near large enough to hold such a vigorous ferment, so i had to jimmy a blow off tube. After 2 weeks it dropped to 1.030 and last week 1.026, today the same 1.026. I shook it 2 weeks ago and warmed it back up to 70 to try and get it going again. Should i re pitch, wait more time or just keg it?
