I have 2 Supers, 1 on each hive, full of honey. Problem is they aren't completely capping it, but don't appear to be drying it anymore either. All the frames have a slight U shape of cappings across the tops of the frames.

Short of buying the cheapest spectromer ($80 bux), is there some way to tell if the honey is more or less done? I would love to go ahead and get this out so I could introduce new foundations for the remainder of the flow.
