It's hemp with orange EO, not just hemp oil. I still think it's worth a try to see if the cloudiness is something that is congealing with cool temps, but it is entirely possible that it's something microbial. If so, I'd expect the cloud to be near the bottom where there might be some water and settled contaminants or maybe the sides of the container where oxygen is more available. The OP doesn't say where the cloud was/is located in the container and hasn't responded whether the cloud goes away by slightly warmer temps. Dunno.
