    Looking at the symptoms of pitting on the surface, I can think of two suspects

    a) cold damage -> Did you leave the plants exposed to cold or cold water?
    b) mite infection. -> I have not seen mite infections on paphs. anyways, check the underside of the leaves for mites. rub a small piece of cotton dipped in isopropyl alcohol. if you see orange/red spots then it could be mites

    I could be wrong with my assessment.

    I do not believe it is the cold and I do not see any pests or I don't know what I am looking for. Assuming mites how would you treat?

    Mites are so small. not visible to human eye. rub a small piece of cotton dipped in isopropyl alcohol. if you see orange/red spots then it could be mites. First narrow down to the symptoms and clues and then get on with the treatment.

    secondly, mite infestation happens only during very low humidity. how is the humidity at your grow area?

    I have 2 Paphs with the same symptoms but being worn under different lights. Humidity not as high as they are being twin inside. First, should I maybe change their location to a greenhouse and second the leaves affected have an orange tint. If all I should do is treat for mites. what is the treatment?

    You can spray upper and lower surface of the leaves with a mixture of 1/3 rubbing alcohol , 1/3 murphy's soap oil , 1/3 water. Repeat it again after 4-5 days gap. Mites hate water and hence sparing a jet of water alone would also dislodge them.
