Hey Growmie,
The info that you researched would be correct, some strains just don't really amber, cloudy is about as far as they go, which is a true indicator that it is time to harvest, also looking at how the pistols turning brown and receding back into the bud is a big give away she's ready. May you have a great harvest and remember ..."Happy Growing" and "Free your mind one puff at a time".
