DOH!
I've missed my window of opportunity for major defoliating and lollipopping.

I don't wanna risk a hermie by stressing the plant with heavy removal of lower branches after I've gone into flowering.
I'll have to wait until next grow to do a heavy defoliation and lollipop BEFORE I flip my lights...ideally 2-3 days before.
I'll still be removing necrotic leaves as and when.
