Hey man! Looking great! those buds are stacking up nice. From your pics the trichs look mostly cloudy, so you’re definitely in the window. If you want a bit more “100% sure” ripeness and a slightly heavier finish, I’d personally wait until you see around 20–30% amber trichomes.
And don’t stress about the white pistils... some genetics keep throwing fresh hairs late, and even small things like strong light/heat or mild stress can keep them coming. Trichs on the buds tell the real story. 🔝🍀
