    Deformed new growth is usually thrips. And if you look in the photo with the N. truncataish leaf.. it's got alot of yellow spotting which is a fungal leaf spot. So I think you have more than one issue.

    Did you just water before photographing? Everything is wet.. are they always that wet frequently?
    Is that a Nepenthes in your pocket or you just happy to see me?

    Just wanted to show a pic of two dark spots on my hamata's leaf. I kind of never really thought about them until this thread. This is the only pic I could find of it, the dark spots are on the leaf with new pitcher. What do you guys think

    Yes, I forgot to take a picture of my N. robcantleyi, which is also going under some stuff. I had just misted the plants, I mist at night and in the morning only, but maybe you're right about them being too wet.

    What do you recommend Tony? Thanks for responding

    Thrips are very mobile and not around when you are looking for them. So any sort of kill on contact pesticide will miss them. Not sure if neem has any sort of residual effect? Personally I would go with a systemic like Orthene, but I don't have to deal with an indoor terrarium. Nepenthes are pretty tolerant to most chemicals so I would just go to the hardware store and find a general purpose insecticide that is non oil based and will work on thrips. If it isn't a systemic type then be sure it has a week or two of residual control after application. Also refrain from misting.. you don't want to wash the pesticide off. Plan on 2 or 3 treatments a couple weeks apart or so.
    Is that a Nepenthes in your pocket or you just happy to see me?

    I second Orthenex, I've used it in the past with excellent results. Also may want to look into a fungicide, I agree with Tony, I see some other potential issues.

    These seedlings ahve been growing slowly for the past year, until a few months ago where they started speeding up. I noticed last week they've been turning bronze-brown colour from green, i don't think its due to light since ligh levels haven't really changed. Anyone have any idea if anything is wrong or is it just me? Could this be caused by overly wet media?
