Is there a slight pinkish tinge on the top there? Could just be my monitor. I can't seem to get rid of the b.linens from the one make I did. Every cheese seems to pick up a dose of them while air drying. I've washed all my mats and things, but as they dry out they get just damp enough to get going. Once they go into the cave, and I don't brine wash them, they don't really progress, but I'm surprised you're not getting any activity.
