    Default Viral infection? Please Help!

    Hi all I am a newbie growing orchid. Today I find these spots on the leaves of my phalaenopsis. She is growing on a balcony facing southwest without direct sunlight. Is this due to viruses? Thank you!

    It is some kind of cell collapse. Your phal may have spider mites. Take a white paper-towel and get it damp. Then wipe the underside of the leaves of this phal orchid. Do you see any color on the towel? If so, your orchid has spider mites. This damage can also be caused from cold damage. I'm not sure where you live, so you will have to decide if it could be from cold.

    cheers,
    BD

    thank you BD! I tried wipping the leaves but there wasn't any colour. It's summer time now the temperature is about 78 to 86F so probably not cold.
    maybe i should try spraying some pesticide anyway?

    Alex, it looks more like a fungal attack than a pest. Does the plant sit with water droplets on it for a while after watering?

    Rayburn, Yes it does! I water by spraying so there are water droplets. Should I wipe the leaves dry after watering each time? Thank you!

    I thought fungal infection, samecas Ray. Try watering in the morning to allow plants to dry before nightfall. See if you can minimize water getting on the leaves.

    Providing calcium to the orchids may help prevent future infections. You can get calcium from many sources including gypsum, calcium nitrate, or a CalMag supplement added to your water. Some people add crushed eggshell to their orchid medium.

    I'm also a newbie but that look like the ringspot virus to me.

    Agreed, but there is no way to tell for sure without testing, so the recommendation of measures to avoid fungal attacks are a way to provide an immediate correction. If the spots stop developing, we guessed right, if not... compost heap.
