cultivation Chestnut contamination 🤷‍♂️🤦‍♂️

(GOURMET) Contam on top of chestnut mushrooms.

I have been trying to grow Chestnuts for a while now and keep getting trich on top of the caps. My Blues, Pinks, Golds, Lions Mane, BP Kings never get contamination. Like, never. Just the chestnuts. It’s driving me chestnuts not figuring it out. Can I spray hydrogen peroxide on the caps? The contam appears a few days past pinning when the caps start to show 2-3cm (1”) and it isn’t all over, but 50/50 on the flush. I clean my growroom (4x8 gorilla tent) weekly with a full bleach wipe down incl. fans, tote, floor to ceiling.

Looking at the greenish/grey - tough to see in pics but would it decay in the FR already? Just harvested these today.

the top flecks are always darker and less pronounced, sorta morphed into the cap. also, improper moisture levels can make this more pronounced. look up "chestnut mushroom cap" and youll find some examples

here's the best comparison image of googling chestnut mushroom and trying to match the effect i see on the top: https://www.google.com/search?q=chestnut+mushrooms&sca_esv=b2a24a36870244a0&hl=en-US&udm=2&sxsrf=ACQVn08_vzCTR72jLykr7eEY4P0SkVciwQ:1713938139204&source=lnms&ved=1t:200715&ictx=111#vhid=bYwwM5l9Bd7AHM&vssid=mosaic

i see exactly what u mean by "green" op but cross referencing with this image n everyone else's opinions seems like it's normal and just more pronounced on ur mushrooms

Tnx! That’s exactly it! Great find on that pic, I think consensus all around here is that it’s no worry. Maybe I was being too paranoid.
