    Default Is it Fungus or Virus? Please help identify these two different problems

    Need help from experts to identify two problems:

    1) Tip of my Cat leaf is black and dry

    2) Phal leaf is yellow on top but funky looking on bottom. Virus, Fungus, or just thrips????

    Please help identify! I am afraid it can be contagious.

    Spider mites on the phal is my guess. Maybe fertilizer burn on the cattleya leaves, but spray with a fungicide just in case.

    cheers,

    Fertiliser burn without a doubt.
    As to the phalaenopsis, my diagnosis would be get rid of it and stop worrying about what it is !
