I’m a newer grower but a couple things I’ve learned:
1. Whole-plant pics help everyone at AFN give you better advice, along with the close-ups of trichs
2. Don’t look at trichome color on leaves, only bud. Leaves have amber changes before the actual bud.
3. Always look at pistil color, too. They should (generally) all be brown before the plant is ready for harvest.
As with everything having to do with growing cannabis, these are guides only, not hard-and-fast rules, but good things to keep in mind.
Regardless, you’re doing great! Keep it up!
