OK before Anyone gives me hell lol...i KNOW airlock activity and fermentation have no correlation. I just thought this was way different then the first two batches. I pitched yeast on the last batch and after a day I had activity in one airlock but not the other ( split batch. ) discovered the non active airlock wasn't st up properly so fixed that and both airlocks went crazy for about a day and a half then just stopped. No slowing down or anything like the others just BLAM go crazy and then NOTHING.
