    I'm leaning towards thrips on this one.

    Come to me flies and crawling bugs. This plant wants to give you great big hugs
    Aren't I pretty, don't I smell good? I'd come to you if I could
    But I can't so you must come to me, I'm sure we will get along splendidly

    Orthene works really well on them, though..... and just abut anything else I've had a problem with, though the smell takes some getting used to.
    Everything has a reason, whether big or small. Never underestimate the power of what is or is not.
    There is far more to everything than meets the eye.

    For whatever reason, hamata seems to be prone to this. I haven't quite figured out what causes it, but it could be heat related (daytime, not nighttime). I've seen it occur on probably three different clones over the course of two years, and if memory serves me well, it always occurred in the summer.

    At first, I began to think that the constant moisture on the crown could have caused problems relating to the water potential of the plant and therefore mass flow, which could theoretically cause these kinds of problems, but I've seen this happen in dry conditions.

    I looked at this thread yesterday but decided not to mention this so as not to sound like an alarmist, but I would go with what pebes said. Although I personally wouldn't assume thrips if this was my plant (they usually decimate the growth point to where it looks black and crisp), I would check very, very carefully for mites (you will literally need magnification to see them). I don't know why, but hamata seems to be an island for these under certain conditions.

    Your temperatures are fine for that species, by the way.

    Looks like I will be purchasing a magnifying glass tonight.

    Thank you

    If it is mites how do I destroy them? And do I need to treat all of my plants? Will the live sphagnum be affected?

    I have some Orthene but it is disgusting...

    Last time I used it I had to repot everything I treated to try to get rid of the stench.

    You can either order a $140 bottle of Shuttle, which is a safe systemic miticide, or treat them with an oil-based insecticide like neem or a pyrethroid. Yes, the mites will go into sphagnum.

    Better still, colonize your plants with predatory mites and skip chemicals all together.
