Your buds look chunky and mature, which is good news. At day 78 on a Fast Bud auto, you’re probably 1–2 weeks away, maybe less. But here’s the thing don’t go off days. Go off trichomes.
Looking at your close-ups, the trichomes still have some clear in there, which means she’s not quite at peak yet. You want mostly cloudy with some amber mixed in. Give it another 5–7 days and check again. The buds look dense and frosty, so you’re definitely close.
What I’d do: Get a loupe or magnifying glass and check the trichomes every 2–3 days from now. The difference between “ready” and “not quite there yet” is usually 3–5 days, and that matters. Too early and you lose some potency and weight. Too late and you get couch-lock vibes instead of balanced effects.
The plant looks healthy, buds are solid, no stress signs. You’ve done good work. Just be patient for another week-ish and let those trichomes finish clouding up. You’re in the home stretch.
Once you see that mostly cloudy look with amber, pull her down. You’ll know it when you see it.​​​​​​​​​​​​​​​​
