You must to harvest with the maximum amount of milky trichomes and very few amber one. The trichomes are fully formed and look milky. Review the seed bank information to ensure you are within the harvest window. If you see that the trichomes are mostly milky, you must harvest. I cannot zoom in enough on the photo to examine them closely, but you should look for well-developed trichomes. Aim to harvest with the maximum amount of milky trichomes and very few amber ones; otherwise, the rest will result in a more physical, relaxing, and heavy 'couch-lock' effect
Summary:
- Milky: The sweet spot for euphoria. This is when THC levels are at their peak. The effect is cerebral, active, and psychoactive.
- Amber: Narcotic effect. The THC is degrading into CBN, which results in a more physical, relaxing, and heavy "body stone" (the famous "couch-lock" effect).
