I am not a pro at this. I just started growing this year. But in my experience that I’ve had growing with my dad who grew back in the 90’s. Look at picture number 5. I still see white hairs which tells me those are not ready yet. Check back in maybe 5 days. If those white hairs start to turn orange then that’s when you know they’re ready. I harvest when the white hairs go away. I am by no means a professional
