When i have a portion of canopy that's overpopulated, i bend the weakest shoot down and under others... could tie it too, but with a lollipop undercarriage, usually save to prop it under something.
good hash/cooking bits later. lots of triches relative to volume and mass.
it's not too late, but a bit borderline. Figure where you see the best buds, give a little room for error, and clear beneath that invisible line. maybe some small shoots that won't produce anything above that line? just depends.
be more conservative removing leaves from canopy, since it's not likely growing back whatsoever -- whatever you take off.
