Looking like heat stress now

Too dry and it will uptake food faster, causes burn and leads to lockout.

Between 41 %- 52% humidity and 17 -22 Degrees so thing that's in range

It's close, maybe a bit more humidity and possibly higher temps.

I tried to follow this chart my last two goes.
A good reference point.

I have found going over .8 lead to too much uptake and then lockout. Especially w strong food ratios.

Can anyone please let me know if these brown hairs are normal or is it mold you think? Any help would be much appreciated
