Try to use the whole plant as a gauge. A few extra amber, or a bit more maturity simply adds to the overall end product, imo. I’ve taken 8 week strains to 12, and 10 weeks hacked at 9. Also, whatever a seed bank lists, add at least another week, or more.

Is the plant still making calyxs with white pistils? Is it still adding bulk to the buds? What’s it’s water consumption like? Nose? Trichomes? All things to when your preferences are maxed out.

Imho.

Don’t age your plant off of the leafs, make sure you’re checking a bract for their trichomes. The sugar leaves age faster.

What was the breeders suggested flower range and are you in it as well?
