Autoflower defoliation 3rd week

Hey i would never remove a leaf that is still full of nutrients and energy. The light that must come to the buds is a mhytos that will never end :-(. Just google photosynthesis. The bud grows through the nutrients that are given to it that contain the leaves :-) the leaves therefore need the light. And even if many persist in the opinion that the buds do not grow otherwise or whatever 😅 I wonder why they cut the leaves off you instead of simply tying them up or down :-)
