In my opinion based on my experience and the experience of a bunch of other hognose breeders, this is a bit on the cool side...
I would bump the hot spot up to about 92 degrees and have the cool side/ambient air temps between 78 and 80 degrees...
Hogs do like it much warmer than other North American colubrid species... In other words, they should not be kept like corn snakes...
It is not normal for males or females to go off feed at any time of the year other than brumation and breeding... All of my males feed year round... I attribute this to the fact they are kept with high basking temps and ambients up to 80 degrees..
