Too wet or too dry is really difficult if not impossible to judge by feel or touch.
If you are using a good hygrometer and humifification(most here prefer Rh beads as they absorb as well as release moisture) and your cigars are smoking the way you like them then you are fine.
If after a month of storage your cigars are going out when smoking then chances are your Rh is too high. If your wrappers are cracking while smoking or you are getting a big cone then you may be too low. But be aware that coning also can occur from smoking too fast causing the wrapper to burn faster than the filler/binder.
