Tommy716answered grow question a year ago From the milky color of your trichomes. I would say that you were at that euphoric and energetic stage of your plants. The THC is high but yet is still not as high as possible. I typically wait until at least 50% of the tricoms start to turn. Amber or change in color. This is all about your personal preference though, so it's up to you. If it was me I would be harvesting within 7 to 10 days. Hope this helps.
Happy farming family!
