How long more to flower

Hey there Paul, Congrats ! No clear, all milky, no amber is the max potency ! it's ready to chop and dry now . Leafs yellowing towards the end of a grow is called senescence , not all genetics and not all plants do it, whether it's there or not is neither a good nor a bad sign. sometimes it comes when the trichs are ready sometimes when the flowers are way past. same with the pistils , sometimes they all stay white. So go off the trichomes , and if you dont have any clears, you're ready to chop any day of the week. Hope this helps !
