Brown spots on phal
 

Hey guys. I bought my phal, which I named, violet a few weeks back and really loved it. I live in honolulu Hawaii and a few days after i got violet, I repotted her to a full bark and sponge rock mix. A few days after that, I realized that the leaves got really droopy so I would water it more often because the bark would get so dry after 3 days. It was potted in full sphagnum moss when I got it. The roots looked healthy but I'm not comfortable with all sphagnum mix. It's sitting on my east facing window and only get morning sun. The leaves never got plump again so I repotted it in a sphagnum and bark mix that I made my own. I wanted it to hold a little bit more moisture because I know that phal does not like to be completely dried before watering again. A week later the leaves looked like it perked up a bit more but then I realized brown spots at the corner of a few of violet's leaves. Does anybody know what causes this? Please help!! I will post picture soon

This is the pic

This is another

I thought it was sun burn so I moved it onto our dining table which gets less intense lighting but bright enough.

It doesn't look like sunburn to me ...
I'm not certain what it is - a bit of fungus, perhaps ... or, if it looks/feels dry, perhaps from low humidity ... :dunno:

Hopefully some other members can chime in!

This is very minor, most likely caused by cold water left on the leaves. If the brown spots are wet and/or mushy, cut them off with a sterile knife blade and sprinkle cinnamon on the cuts. Then be careful not to wet the leaves when you water, and wipe off all water as soon as possible.

Thank you! I just cut the brown spots off with a pair of sterilized scissors. I also sprinkled cinnamon by the cut area where the open wound is exposed. Thank you for your prompt reply. There is another leave on the other side that looks blotchy with slight yellow tint in the middle. Should I be worried?

There are two possible reasons for the yellow blotches: damage from mites (very difficult to see the insects themselves), or cell damage from cold water on the leaves. In either case, there is nothing you can do about leaves that are already showing the damage, but just to be safe, I would spray with a (lukewarm) miticide once a week for the next 4 weeks, and avoid any water on the leaves, especially cold water. I'm dealing with cold water damage right now as well, and I've been spraying miticide just in case.

switching from moss to bark can be a bit traumatic for the plant...sometimes certain plants take it harder than others....also, I hope you soaked the bark before repotting, if not, then the bark isn't holding water for the plant to use, it is just 'repelling' the water so the plant doesn't get any....repot again, check the roots cause they obviously aren't working very well...keep in a shady location and water only after a week or ten days....you have to let the roots heal before watering again....good luck!

Yeah I really soaked the bark before repotting it. It seem a lot better after I mix the bark with sphagnum moss. The leaves have since been more perky and doesn't feel rubbery or dry. I think it's definitely adjusting itself to the new medium. I'm just waiting for the flowers to all die off before I cut down the spike. I heard that this will 'tell the plant' to start growing new leaves and roots! But until then, I will enjoy the flowers while it's in bloom :)
