    Exclamation Oncidium S/H update + leaf spots! (HELP PLEASE!)

    I acquired an Oncidium on Feb 23rd of this year, it looked fine but the root mass wasn't at its best condition. I placed it in a S/H medium. This is my first attempt at growing an Oncidium. it's getting plenty of bright light and no direct sun light, it's been outside since a month, the pot is flushed weekly.

    Lots of new roots have emerged since then and there's a growth of a new bulb and the growth of a new leaf.





    However there's something wrong with the leaves, brown spotting is emerging at the tips and around the edges, can someone please help me with my problem.









    There are no test kits here in my country, I have neem oil and alcohol, to speed up your answers.

    Thank you.

    Some spotting (looks like black freckles along the leaves) on onc. type orchids is normal, but it looks more like you have sunburn. I hope someone with more experience can give you a better answer...

    I had the same thing happen to me a few months back, http://www.rv-orchidworks.com/orchid...emergency.html, check my old thread and see if there's anything there that may help you. Hope It's nothing serious, good luck.

    Looks like a couple of things going on to me. First, the tip of the leaf turning brown could be from excessive fertilizer (salts) build-up in/on/around your orchid plant's roots. The issues down the leaf look more like sun burn caused by perhaps water or oil magnifying the intensity of the sun on the leaves. JMHO. I sure others will offer a different opinion.

    cheers,
    BD
