Hey :-) Look with a microscope 👌If the trichome heads are about 70% milky and 30% clear, you can start with the flush. If the trichomes are about 70% milky and 30% amber, it is a very good time to harvest 👍🙏🏻 but do not pay attention to the leaves of the trichomes on the buds 👍Your plants looks great👌
