To me ... The problem about weight , is that it looks like you did some ( pruning / defol ) on her .... No lower fans and areas show cuts.
AUTOS hate stress ( they are mostly plug and play ) . Cutting fans is like pulling the plug on energy for the plant. They stunt very easily. And it looks like there was some burning on top of it. Autos can produce 200 - 400 grams ( average ) with SUPER AUTOS making much more ( 5-6 foot plants ) .
Just my 2¢
