    As for the other Nep, I am thinking immediately that it's sunburn but am not sure. Does not resemble any kind of nutrient deficiency at all. I am wondering--was the plant moved at all recently, whether by you or knocked over by animals? It looks to me that another leaf of something developed over the area that is burned, causing the leaf to look slightly paler than the others and making it more prone to burn. Tropical sun can probably easily do this if so. Did it develop in the shade, or perhaps a tree dropped a leaf on it? Also--did that particular leaf develop in your care or the original grower's? It is likely that something like I described above happened at the nursery, since often plants are crammed together. Was the nursery in the tropics or temperate zones (i.e. how strong was the sun there?). The plant may have been shaded there, been removed and shipped to you with that weakly developed leaf, and been prone to burn from the very beginning. The rest of the plant, IMO, looks perfectly healthy, nice thick sun-adapted leaves, and I don't expect you should have future problems as it grows out. Hope this helps!

    This next one shows a very similar pattern (marginal burn) on a range of species

    Thanks everyone for the info! I'm going to see how the new leaf developes on the bical and go from there.
    I moved the spectabilis to the cooler side. I'll see if this helps any, but if not it might be up for trade

    N. bicalcarata is notorious for disliking change. Probably just the original leaves showing a bit of adverse reaction to the change. If you start seeing the same symptoms though on leaves produced in your care then there is clearly an issue to be concerned with. Perhaps as suggested, some sort of nutrition thing but with N. bicalcarata it could be environmental also. Yes it's also possible that the much smaller seedlings next to the larger plant are not as affected. They tend to be more forgiving than the large size plants of this species.

    Oh woops forgot to mention the N. spectabilis. Looks like that one leaf has typical sunburn. It also appears to have moisture stress.. the offcolor green, the somewhat curling under of the leaf edges etc.
    Is that a Nepenthes in your pocket or you just happy to see me?

    Interesting, I didn't realize they were so picky with being moved, that might explain a little. I did move it over about three feet, which seemed like nothing, but now that I'm thinking about it, it probably is different in sunlight from where it was. I also figured since it was bigger it would be hardier than the smaller ones that I also moved. I learn something new every day!
    I'll keep an eye out on the new leaf and also be even more mindful of the spectabilis watering and see if that helps.

    Update on the bical: Looks like the newest leaf it super happy and will also make a pitcher. I'm thinking that small move must've cause sun damage and that's what the chlorosis and browning was.


    The spectabilis still looks the same but I guess not declining in health is a good thing.

    Looks a lot better. That's going to be a beauty when mature!
