Hey Growmie,
Buds are ready to harvest when hairs have darkened and curled in, revealing the solid bud underneath. Harvest buds on the early side for more of an “up” mental/psychoactive effect (trichome heads appear milky white under a magnifier). If buds are allowed to continue maturing, the white trichomes begin to turn amber/golden. The greater the number of amber trichomes, the more buds produce a “down” body/couchlock effect. Looking at the pictures you still have quite a bit ways to go. Hopefully, I answered your question and remember Happy Growing and Free your mind one puff at a time.
