I brewed my first batch, a simple cream ale extract. Got it into the carboy, but made a mistake and put the ferment lock on right away instead of the blow off hose. The next day when I checked on it foam had blown the airlock off and made a mess. I put a blow off hose on and let it sit. After 4 days there is no more action from the blow off, or the ferment lock and the foam has crusted inside on the top. According to the recipe I used there should be action for 2 weeks. What should I do?
