Those aren't ready, I'd say at least 2 more weeks. What strain? What's the breeder say about flower time. Figure a week more than they say. I've yet to see a stain that actually finishes when the breeder says. The supposed 8 week strains go 9, the 9's go 10 wks. Environmental factors also pay a role. I have a blueberry I've been running for 2 years now, always finishes in 63-65 days. I'm running it in a new tent, totally new setup I'm dialing in, and I can tell she's about a week slow from where she should be.
I have a have a HSO green crack that was showing amber beginning of week 8, it's a 10 week strain, amber isn't the only deciding factor. You need to look at the whole plant, all the little signs. The majority of pistils will start receding into the calyx. The calyx will then start to swell. This is when you start watching for the trichs to get milky, not just a little cloudy, but milky. It's a daily core checking them at this point, you need to decide if you want 50% milky, milky and amber, or wait for it all to go amber. They change quick at this point, sometimes going from some milky to all amber in a few days.
