well a plant i saw once got burned right on top, it was touching a cfl...
But it started new growth. believe it or not, it has 5 new tops. they are coming out directley below the broiled part lol.
Leave em, some might even get better if they aren't crisp yet. In my book you aren't really trying if you don't have at least a couple small bleached leaves, yours is out of control though.
