Slightly worried.... One of my smaller batches is rarely bubbling... Maybe 4-5 bubbles per minute. Looks like the yeasties have slowed down, i dont even have a bubbling layer at the top anymore... Its only been going 1.5 wks. What should i do, if anything? This one has the blow off line, as it was originally going to explode 2 days after starting.... I hope it'll beokay
