I brewed an IPA 2.5 weeks ago. OG 1.075 and it's only fermented down to 1.020. It's st fermenting and the air lock is bubbling every 8-10 seconds. Why would this fermentation be so slow? Same recipe usually gets down to 1.010 in a few days. Mashed at 150. Yeast is London ale 3. This is second generation yeast washed from last time I brewed. Is the yeast just weak? I didn't do a starter because it was about 2-3 times the amount of yeast that comes in a package. Should I pitch more yeast? It's been fermenting at about 68 degrees
