I know that some Neps do react to cool weather by producing spots like you
described. But if it is cool enough to produce spots its usually not too
far from the temps necessary to cause curling and browning of the newest
tender growth. If you have your plants outside in St. Pete, you could
easily get temps low enough for the spotting.

     I have recently obtained a few Nepenthes with red blotches on alot of
the leaves. I was told this was due to cold damage. Until this time I have
thought these red spots to be the result of a fungus (rust) which other
being unslightly wasn't a threat to the plant. I had never heard of the
markings due to cold temps. I sometimes get these dark red spots on plant
leaves that have not been exposed to cool conditions.
     While at a bromeliad nursery the orchid grower had some N. x Coccinea,
some had the red spots which he tried to tell me was a varigated leaf! But
these plants did have damage due to cold.
      Could anyone offer comments on these spots?
