There can be wild differences in different strains. My favorite girl looks just like yours, and she never goes amber. She will be as hard as Chinese algebra but will continue to throw out white pistils. Got so dense when I tried for 12 weeks, I created a bud mold problem. If you have cloned her, make a few notes and carry on. Also breeder times are not worth much, whatever they claim, it's usually 2 weeks shy. I'd go longer, but do watch for mold issues. Good growing...
