Hey there , some genetics have trichomes that turn milky slowly , or even turn very light beige color instead of amber. Maybe it's one of those genetics. She seems to have started foxtailing a little bit , probably from being left to flower for so long. The main thing is to make sure you're looking at the trichomes at the right magnification 60x or more, at lower magnifications than that the trichomes always look clear or milky. But yeah nothing you can do to speed it up, one thing to know is that trichomes take an average of 2 weeks to reach maturity , sometimes they all become milky overnight. The only thing you can do is keep checking and stay patient. Hope this helps ! 🚀
