@FraFra__frankenstoner_Dont_panic_its_organic, Hi ! because a plant need active leaf for photosynthesys even at very late stage.
There are enought PPFD here. Photosynthesis, and vapor pressure are the key. Defoliation come here to de-stock the nutrient a bit, during the ripping phase.
the photons conversion need power, and it comes from the leaf, not the fruit.
