Not nessessarily. Once the buds swell and the orange hairs receede, you know she's done.You'd need a magnificent glass, just look at the trichomes, if they are milky then you can chop, if they are transparent - then wait for a week
Is this mold!!!!????If you have dead leafs remove them mold will come.no harm done if you precut a few tops you will have something to smoke until rest finishes
