thanks for all the responses and i know about the 30X magnifying thing, however i have not purchased those as i'm making this as cheap as i can so i decided long ago to just go by pistil color and bud look. the the method i decided to take.

thanks DYLAN for your answer, that was my main question i was looking for an answer for and assumed it was the chlorophyl and i also assume the chlorophyl will break down and the sweet bud smell will start to come back. i just wanted to confirm that theory with other people.
