Went to do a gravity on my first all grain brew. A wheat beer using Safbrew WB-06. It's been 2 weeks in the primary. Maintained at 64F but did have one day it's temp dropped to like 54F. It's OG was 1.052 at 70F and today gravity was 1.024 at 64F. It smelled like all my other extract batches but looks horrible. I'm thinking maybe I fermented it too cold so the yeast are not able to do their job? I could not get the courage to try a taste. Here is a picture. What should I do with this? Raise the temperature maybe? Stir it up to try and get things moving? I would imagine if it was bad it would not smell normal.
