I opened up one of my humis and noticed a diesel with one singular white patch on it. Not 3d and fluffy and not sparkly either. It was 2 dimensional and wiped off easily with a wet finger. It kinda looked like a toothpaste smear. We've been getting hot weather so I put my humis in my basement to get it cooler but it's so friggin' moist down there the rh spiked to 80 and it took a break in the weather to get it back down. It's better now and no other sticks look bad. Mold?
