Fahrenheit Herbicide is not labeled for cool season turfgrasses including Kentucky Bluegrass to control poa annua. For poa annua, we would recommend making a fall pre-emergent application (if you will not be overseeding), you can use Pendulum 2G. Because poa annua is technically a cool season grass as well, the only option you really have is to use a non-selective herbicide, like Roundup QuickPro to make spot applications and reseed those areas.
You can also review our Poa Annua Treatment Guide.
