Removing dry, necrotic leaves

I would definitely remove the burnt edges. It's going to take some time but put it up on a table so the plants at eye level. Smoke a fat bowl,joint,blunt, all the above and sit down and start trimming them off little by little removing them as they fall. It will make trimming easier when its time for the chop and reuse of the trim material. Really just going to have to do a little at a time and before you know it they'll all be mostly removed.
