for the swelling, (too weak to be sure), I would say: crystalline white = transparent. and dull white = milky. And if you notice amber, which is not the reflection of a pistil, usually on the edge of a sugar leaf, then there is a good chance that it’s good. I would say another 2 weeks, just a guess.

You look like your I'm ripening stage. About a week left hard to tell with just one picture. It is about 1 to 2 weeks after most the pistils turn brown it is ripe. Most cases. Good luck and enjoy

Easy less accurate way is harvest when 90% of the white hairs have turned red. Inspecting the trichomes you need a jewelers loupe or microscope. If the top head is: Clear = low thc Milky= highest thc Amber = degrading thc

High Ilgm123, The trichomes are still clear and shine like glass. When they get milky cloudy than it is time to start flushing (only give water without nutritions so the plant can use it's own nutrition storage). And when the first trichomes turn into amber collour it is ready for harvest. You can use a pocket microscope x60 to check the trichomes precisely. They are cheap and really usefull for checking trichomes and pest identification. Happy growing and happy harvest! 😋

Relax... I don't know how old they are but you've got at least 3 more weeks... your trichomes are still pretty clear. Good luck!
