    Hi all!

    I recently got a new place and have been busy decorating it with lots of plants. Recently, I added the beautiful Alocasia species to my living room and I absolutely love it.
    However, after 2-3 days of bringing it home a few of the leaves got small yellow dots on them.
    At this time I checked the soil and it was dry a couple inches deep, so I watered it. The leaves for the next day proceeded to 'weep' and expel water drops through the tips.
    Now, 2 weeks later, the yellow dots have not gotten bigger or shown up on any other leaves.
    However the youngest leaf turned completely yellow and died. And 2 other leaves look sort of paler green, and are softer/floppier than the others which are quite stiff and dark.
    I have the pot on a plate of wet rocks and mist the plant every now and then to keep the humidity up. The room gets a lot of bright indirect light.
    I thought because the leaves were expelling water perhaps these symptoms were of overwatering, so I let the plant dry out the past week. Could the problem also be with fertilizer or lacking some nutrients? I have checked for insects and there are none.

    Any advice is much appreciated! I really don't want this lovely plant to die! I have other Alocasia species and they are doing just fine.

    The dots of water you describe are guttation. This occurs with a number of plants but quite often with aroids. It's normal and not an indication of overwatering. It's part of the normal respiration of the plant and will typically manifest with numerous drops of water in the early morning along leaf edges. Depending on local humidity, it isn't always apparent.

    The yellow dots could be fungal in nature, but could also be incidental insect damage, or spray mist from household products. If they don't get worse, I wouldn't worry about it.

    The pale leaves are likely due to lack of light. You may think you've provided enough, but Alocasia spp. live in equatorial brightness, even under forest canopy.

    Hey, thanks for the response. I moved the plant nearer to a window, and was watering once a week (soil was moist but with good drainage). However I have lost two more of the small leaves and the last is turning yellow. I thought maybe I'm not watering enough? The guttation has completely stopped. I watered now twice a week like my other Alocasia. Plus daily misting.
    This week I have moved the plant to my sunniest room so hopefully that helps. Here are some picks of what is still going on: smaller leaves turning yellow, larger leaf veins seem pale and some yellow areas on edges.
