Just did my first biab okto clone hit my og spot on at1.050..... Pitched wyeast 1007 package didnt fully swell. 2 days later started fermenting like normal. 6 hours later it just stopped!!! So left it alone for two more days not a single bubble out of the airlock! So i thought it may have stalled . So i pitched another smack pack same 1007 again package didnt really swell! Took a gravity reading three days ago and today its at 1.026. Any ideas?
