    Default Disturbing Leaf Spots (pic)

    I haven't had leaf spot problems for a while and suddenly I noticed some today. They're on an oncidium intergeneric (mtdm), and the concentric circles disturb me. It receives a good amount of afternoon sun but it shouldn't be sunburned because the spots are only on the leaf of the newest growth.



    Any idea what exactly is this? Looks like an infection...

    some ideas...
    - spots due to the sun but concentric circles are stange in this case maybe with water drop on leaf
    - spots due to a treatment received by the plant (insecticidal...)
    - spots due to fungus ???
    very difficult to say

    I to grow oncid alliance and going by the look of the spots ,to me they resembile water having been on the leaf.
    If the spots are dry then all is ok,but if they are soft and mushie then mix up a fingicide and spray the plant

    Thanks everyone...they aren't mushy so I'll stop worrying about them for now. Yeah, it's possible that I accidentally dropped some water on the leaves. Good thing they're nothing contagious .
