The brownish aborts look like bacterial infection to me - not enough air movement, and or, they got really wet. You want high RH but you don't want the things to remain wet very long. Maybe Pseudomonacae. Frankly, you are on the verge of growing plenty of mushrooms, good mushrooms, Personally, I wouldn't eat anything that had the chance of making me sick AND high at the same time. We play with all sorts of nasties at the microscopic level when we grow mushrooms. We can inadvertently bring a slight concentration of a few harmless little bodies into the realm of toxicity and danger. For instance, Aspergillus Niger or Aspergillus Flavus scare the PISS out of me. If I even imagine I have a case growing I will toss it all in the cooker, steam it for an hour or so and still use a mask when I get the stuff out of there. I recently read a recounting of a guy who just went outside and cleaned his jars of who knows what, no precautions no nothing. He is quite certain that he can attribute a host of lung disorders to his having done so. Whenever I am unsure, it goes in a sealed bag, it gets steamed and then goes into the trash.
