/diy/ - Do It Yourself

I've heard tell of pellicles or some such nonsense and sour beers and such.. Might that be what it is? The fin was much more uniform, before I stuck a wine thief through it... Should I re rack this? Let it sit longer and see what happens? I'm about to be out of town for a month, so if it is a legit bad infection I don't really want to just leave it..
