First of all Jerrya...
Is your hygrometer a digital one???
If not stop right there and buy yourself one...
The Western Caliber II is the best by far and cheap...
If it is a digital then it sounds like you might have a common
problem everybody has which is getting it too wet!!!!!
The cigars that is....
Try dropping to 65-70% humidity and make sure that your humidor is in a more stable TEMP environment...
In other words you don't want to keep it in a place where in the morning the temp is 25 degrees then by midday its at 85 degrees (dramatic example to prove a point)...
Otherwise check the humidor for leaks...
