Hey guys! I need your feedback for a friend who is trying to grow for the first time. He bought a grain spawn 2 weeks ago and now he’s stuck with gray pins and it’s been like that for 4 days. From my experience pins are always brown but I’ve only grown a few times. The strain is Mexican psilocybe cubensis. Thanks! #3 Shroomok: Hey, if pins stop growing and turned grey or black it can be mushroom aborts
