  Congrats on your first successful grow! Good job and thank you for sharing 👍They look great, just some Mycelium Bruising here:Mycelium bruising area – possibly due to hard fanning or mistingAnd mild Bacterial Blotch on a few caps here:Bacterial blotch – soft wet dark-brown dots on mushroom caps (in blue circles)But don't worry, they are absolutely fine.
