    Doesn't look like nectar glands to me because of the lighter tissue color around the dark center. Also because they are usually on the underside of the leaf and the spots look to be on the topside here.

    I doubt it is burn from moisture droplets getting hit with sun in this instance.

    I am not a pathologist but it looks pretty minor and is most likely something like Botrytis from excess moisture. I would only be concerned if:

    The existing spots are getting larger.
    Or
    There are more spots showing up.

    Is that a Nepenthes in your pocket or you just happy to see me?

    Hi all:

    Interesting questions!!. I hope i have interesting answers!!.

    First of all, the spots go right through the leaf, not just on top.

    No they are not growing, they just remain the same size. One curious thing though: the edge of the leaf have the same spots, but cut in half, like half circles!!.

    Older leaves and newer leaves seem to be free of these spots so far!!.

    If you have more questions, i'll take another picture later.

    Thanks

    Gus
