Should I cut the cheese?!

Got a confidential cheese that is 3 days away from 8 weeks into flowering.(Vegged it for 2 weeks) The buds are large and ROCK hard! The only problem is that the majority of the hairs are still a milky white, Id say only about 30-40 percent is amber hair. How do I know if its ready to chop? I flushed it about a week ago so id be able to harvest on the 8 week mark...but i dont think that will happen :(
