Time to harvest?

no

They still look very clear. You want them to ask lol full and cloudy, that's when they're at their best. When you start to see around 15% amber, you'll notice that most of the others are all cloudy/full/creamy

agree with john kramer 👇

For an uplifting effect you want the trichomes to be cloudy, around 80%. Your pics are hard to determine where they are. One pic looks all clear trichomes and another looks 50% amber which would be past harvest time. Amber trichs are easy to spot, the head will be distinctly golden to brown in color. Check a few different colas/buds and if you see one amber in each area that's when I harvest. Some people say the calyx will be swollen and I find that hard to tell with my grows. There's a learning curve to harvest times. Are all the pistils brown and curled? Some strains may continue to put out new pistils. Pics of whole plant or buds could help since your pics may have light refraction going on. Good luck

there is some amber, so u can flush and harve after dry back
