Defol for lower/inner buds ?

nah. use LST is anything, keep up the airflow.

From personal experience I have never defoliated and noticed the cola get bigger, its always 100% time smaller than the cola I cant reach to defoliate. Whatever magic I manage to convince myself im helping by defoliating has been just ego to make me feel like im doing something useful.

Hello mate, your plants is very vigorous so i think you could take some leaves to let in the light also in the lower buds. This probalby don't give you a lot of extra weigth but it could let ripen your buds at the same time. Good luck and happy harvest!!

What is nice and looks esthetic for human eye - NEVER works for plants. I dont see what you could take off. Plant have hierarchy in leaves and prioritize top ones for photosynthesis , bottom ones works more like storage, despite still producing energy for plants. I tried to simplify for you to understand.

Ja das kannst du machen. Ich tuhe meine autoflower und Photos immer entlauben wenn Blätter größer Bud verdecken oder damit mehr Licht an die unteren Buds gelangt. Aber halt wirklich nur die wo stören.
