They are in a harvestable state. It's a preference thing at this point. I just harvested my plants that were starting to look like this. They are indica-leaning hybrids and I prefer a more head-high. I didn't want too much more turning amber and they will start to turn more amber as time goes on from natural degradation, But I only had two plants. depending on how much you are relying on them it may be worth letting them go longer to see what happens. would also be helpful to have an overall picture of the buds too just for perspective. My leaves also started to turn purple and all the "hairs" were orange. Also noticed the riper of the two plants drinking less water the days leading up to harvest.
