I see 3 sources of possible herm-inducing stress:
-Ice-water bath
-Overzealous pruning
-Light leaks

And a note about 'aborting' seeds... IMHO, a crop seeded by fat, ripe, brown seeds is far preferable to a crop seeded by immature little white pips that you can't find and remove before smoking. The ripe ones are easy to remove from your finished product. So just go with it, fix your problems, and better [more seedless] luck next time...

BTW, does that Critical Mass stink like two skunks fucking?
