You are doing a Kolsch, using Kolsch yeast with ambient conditions in the low 60's....that's perfect! Kolsch is an ale that wants to be a lager. A long cool fermentation is desirable. Don't rush your Kolsch. It sounds to me like you have done a nice job with this one....I love Kolsch
Something is always fermenting....
