Mine have gone cloudy on me and ive had no problem at all.
They still tasted good. Usually the ones that got cloudier seemed to be further along in the pickling process. Some times a film will form on top. Just kinda scoop that off, and the pickles should be fine. Even though u used the same recipe and ingredients for all, its still not an exact science, as the cucumbers are different sizes or whatever. So some might advance sooner than others. My current batch is about 3 days old and ive eaten about 1/3 of them already
