Cannabis leaf morphogenesis, phyllotaxy, plant architecture, reproductive transition, inflorescence development, trichome development, and senescence across a complete life cycle.
Visual lesson 10
Maturation, senescence & bract change
Follow bract expansion, stigma condition, glandular-trichome maturation, resin-head aging or dehiscence, and surrounding tissue senescence as partly asynchronous processes influenced by genotype, flower age, and sampling location rather than as a universal week-by-week harvest clock.

Asynchronous bract, stigma, and trichome maturation sequenceStart with the highlighted plant system as the anatomical context. Then compare the lesson observations with the evidence sources and knowledge check below so structure, process, and whole-plant consequences stay connected.- Plant system

PracticeCan you explain what the visual is showing?
Why should flower maturity not be assigned from one calendar week or stigma color alone?
