Im with the majority those plants need atleast 10-14days before you harvest, I really dont see the amber trichs your talking about, but you can clearly tell from the bud structure that their in the last couple weeks of flowering, I would shoot for another 8-12days, maybe even a few days longer. Not sure where you are in your flush, but if not you should start flushing, you can use some molasses if you want, otherwise just straight ph'd water. Try to time harvest on a day where the plants would absolutely need watering, meaning very dry soil when you harvest, it will cut down on your drying time. Another practice Ive adopted was giving the girls 24-36hrs of pure darkness before chop, cause supposedly there is more trich production during the dark periods, which I have to say it does seem to pack on little extra frost, but it could just be a new superstition that I do before harvest. Your plants look great, nice and healthy, I would think you would have a lot more yellowing in your leaves if you've been flushing. So im humble opinion you have a minimum of atleast a week, depending on percentages of trich color and your personal preference you could prob wait another 14-20days if you wanted that good knock you on your arse high. You could always harvest a plant a little earlier than others and see once its all dried and cured what smoke you like the best. Plants look great, well done my man, peace!
