rhizome, have you read of CA problems showing up as veins browning, and then spreading from there? If so, can you direct me where? What about my photo reminds you of a CA problem? Too much CA or too little? What sort of thing do you think might have caused this?

killerweed420, maybe you are referring to my pic 10. Yes, that is one of my Purple Big Buds that was *not* wrecked by this problem -- I was trying to show that it didn't ruin all my plants, and I agree that one photo shows a normal life cycle thing.
But what I'm puzzled about is the ~40% of the plants that lose ~ 3/4th's of their leaves to this onslaught, and who's yield is less than one-half of their unaffected companions. They are not going through a normal cycle of life because I can see how bad they are doing compared to other same-age Purple Big Bud plants in the room.

Any thoughts?

Still perplexed,
