Looking for some advice here. I am currently fermenting a pliny clone, and have not noticed any strong signs of ferm. I noticed bubbles for a day straight on day 4 (after stuggling with blow off tube suckback, more than likely caused by the 58 degree temp?)and that was it. I have not had any kraeusen, or activity on the top of wort. Should I pitch more yeast??? Any advice would be appreciated. Thanks
