Can I cut it back now, because the blooms are very gray and unappealing? I am in Ohio and it has been extremely hot. I have a lot of new growth at the center of the plants.

Yes, you can remove blooms that have faded at any time. In Ohio, oregano will die back during the winter and return next year, so it is not necesary to cut back foliage for the plant's health. However, it is fine to cut back the foliage now if the older growth has become unsightly. Make sure to leave some growing foliage (the new growth you mention) so the plants can store energy before the winter comes.
