    Default splotchy/mottled phal leaves

    Hi everyone,
    Could you please tell me what you think has caused my mounted phal leaves to become splotchy/mottled? They appear somewhat 'water-logged' in spots, but are not quite so much when touching them as they appear. They are also more droopy and shriveled than they should be....a look of not enough water or nutrients getting to them.

    I mist the roots usually once-twice daily with the same fertilizer/water that I soak my potted phals in. The potted phals do no have the same leaf problem. They look healthy. The exception to my watering regime is the forth week during which I mist them with clear water each day.

    All four of my mounted phals looked healthy and bloomed nicely in the late fall/early winter, but their health began to slowly decline afterwards. I assumed that they had basically 'bloomed themselves to death' and would snap back, but they didn't.

    All four phals had developed a healthy root system, but look rather shriveled and dessicated now. Being late Spring/early Summer, I have been hoping that new roots would take over and supply the plants with what they need, but few have grown.

    I will appreciate any advice. Comments welcome, as well.
    Vicki

    Do you fertilize with magnesium? Could be a micro nutrient deficiency.

    This looks like an issue of dehydration and NPK deficiency.

    Vicki, I would guess that misting is not getting the roots wet enough. Try soaking the plant, mount and all, until it is thoroughly drenched.

    Thanks Ryan.
    I've tried to soak them in the past but the problem I've had is that the mounts are cork, so they float (rather than submerge). The majority of the roots are on the front and I've been afraid to turn the mount upside down to soak the roots because I didn't know if it would be ok for the leaves to soak in fertilizer water ???

    I would rather recommend tie a little bit of moss or coconut husk around the roots, so that it allows some more time for the roots to absorb the water.
