This is a great thread! You tell that hubrackin dude to get bent Luda! By the way, take a better picture if you can so there can be more "discussion" on the subject. I personally have a plant that had the calyx closest to the stem and fan leaf turn brown but never swole or anything. There was no seed and all of the heads were still white, I think the plant stops supplying those inner/older preflower with the life juice. I may still have one on there and if I do I will take some pics then remove it and disect it while taking close ups of everything.
Hope this helps. Damn HUBRACKS! ....lol
