I believe it is an indicator she is winding down, I know Doc says he has had a hard time getting the trichs to go amber. Don't know if he managed to get them to cloudy, maybe he will chime in. I know some strains will continue to shoot out white pistils regardless of how far along they are. Perhaps some others here will clue you in to other indicators of finishing besides trich color and pistils.
EDIT: I know the pics Doc post look like cloudy trichs however.
The triches on my plants are clear and cloudy. Rarely do I get amber.
