Athosanswered grow question 6 years ago Check bud photos on google. See those white dots that give them a frosty look? Those are thricomes, what you want is for most of them to look white / cloudy; it's not easy to tell between clear and cloudy, you'll need a bit of practice. Once your bud's calyxes swell, you will be days from the peak thricome maturity. In case you don't know, calyxes are where, if pollinated, seeds would form, in the photos they look like small balls on buds. Hope that helps
