I’m not sure if this is mold in the first two pictures or hooch volcano. There’s no pink, orange or black colour. It doesn’t smell bad, it just smells like flour. But I’ve been very inconsistent with feeding because life has been rough recently and it’s been in and out of the fridge. I fed it this morning and after four hours it hasn’t rose at all which is not typical. Usually it’s peak now. 3rd picture is roughly 4 hours from feeding. Help please
