Well yes, let me report I have an exact problem such as your truncata Ken. It's supposedly some sort of a fungal attack though I do not keep my plants in trays. But I will relate the story, in a nutshell, of how I found out eventually:

Problem started when I placed my then healthy truncata on an upturned pot, exposed to full sun and rain. After a third leaf and pitcher, the fourth started to unfurl but not before having rust spots all over. Needless to say, the crumpled effect began to take shape and the pitcher turned out small and lidless. It began to get worse until I, unaware of anything, one day decided that the truncata was no longer revivable and shifted it to another spot in the garden. In two months time, the plant resumed normal growth. Tempted to reaffirm the suspicions, I moved the plant back to the old spot and sure enough witin a month, the spots reappeared. Now I have two plants and both are placed away from the spot (only a meter or two of distance, believe it or not) and not one has got a red spot since.
