Washed out and left to sit (open) for about a week before filling. My office in the basement is in a corner with no window, no heat source, just an unused room I store my hobby junk in (guitars, golf clubs etc...) no heat sources at all.

I've had them open now since about 10 pm last night and the "fog" hasn't dissipated at all. I wiped some with my finger and it almost does feel a bit oily, so maybe empty them out and give them a cleaning?
How's the ambient rH (relative humidity) where you live? They're closed jars but basements can be moist and if you closed them there then the air inside the jars might have been moist.

On the surface it does sounds like heat, perhaps sunlight. Doesn't take much sunlight to cause some mist and there'll be more if the tobacco is moist and less ability to reabsorb it. I'll ruminate and see if I can think of anything else.
