Looks beauty mate, why you wanna defol? Any reason? If airflow is good it's fine. Defoling will slow growth slightly while it recovers. 11 wks, you sure it's not a photo? Looks the same at 8 wk as it does at 11. Only ask because it has been known for autos to turn out to be photo, or idiots like me plant photo instead of auto and don't realise for 7 wks, Ahem ; ) . Having said that, it's a big pot so would've taken a lot of time to spread roots out.
