Paph leaves looking sick/sunburnt?
 

Hi
I recently bought this paph it seemed to be doing ok until I moved it to a spot closer to the window. (even though we've had little direct sunlight lately) I've moved it back away from my other plants in fear it might have a bacterial or viral issue. Or maybe just sunburn? I have limited experience with slipper orchids. Thanks for the input

I grow exactly one Paph and mine sometimes loses those small bottom leaves so I was hoping someone else could help you with this.

It could be normal or it could be that some water got on the leaf and you have a fungus infection. I usually treat this sort of thing with Isopropyl alcohol and, if it spreads, remove the leaf.

sprayed the plant with a 3-in-1 just in case and moved it well away from windows. the rust coloured spots on the larger leaves are worrying me also.

Are the spots increasing in size?

Spotted Paphs prefer less light than other Paphs. They are shade plants. They shouldn't be too close to a window if the sun is at all bright. Even an hour or two of direct sun might burn the leaves, though this is less likely this time of year.

Also, check the temperature near the window at night - it might be getting too cold.

This kind of spot can also happen with irregular watering. They prefer to be regularly moist, but not wet. If they dry out too much and too often, this can happen.

I can stake my life on this: It's not sunburn. And while the only way to confirm this is through testing, the plant is almost certainly not virused and these symptoms are not virus symptoms.

The plant is adapting to your care and growing conditions, so some leaf loss and stunting is normal until it adjusts. However, I'm seeing up to 3 - 4 leaves at least starting to yellow. At the very least, you should inspect the roots and see if they're in good shape. Generally when there's this much leaf drop/yellowing, the roots are not in good condition.

Repotting may be required and then you should evaluate your growing conditions. They may be too wet. Or your potting mix may not be appropriate. Or other care you provide may not be sufficient. But we don't know how you care for it, so it's impossible to really say for sure.

I've moved it back away from the window. it came to me in spag in a soft plastic covering i've repotted it and its counterpart into fine grade orchaita, perlite and spag. its roots looked ok . not phenomenal but not totally rotten either ( i have one of those in ICU at the moment with no roots left at all). the spots haven't changed noticeably over the last few days.. im keeping it away from everyone and added a bit of cal mag to its last watering. other then that its wait and see i guess. its not seeming to stay too wet too long after watering so i'm hesitant to disturb it so soon after a repot. (the little one i bought with it is totally fine except for too much sun exposure on its flower causing damage)

Its looking much worse :( i cut off a lower leaf but really don't know what else to do? ive tried alcohol, 3-in-1 any more ideas? I hate watching it slowly die :(

Note I also found some mealy bugs when i cut the flower spike off of it. they seemed to stay on the flower area though no sign of them down lower...

Looking at your last pictures, I find this looks like your rhizome is rotting... Your mix looks pretty wet. Paphs don't like to go dry, but I'd suggest creating some air gap around the base and keeping it on the dryer side. This shoot will not exist a year from now based on its current condition, but that's fine all you need is for a new one to emerge and treat it right! Good luck.

I just watered it before this picture was taken but i moved the media back a bit from the crown. im pretty much willing to try anything to save it, I loved the flower and the leaves are gorgeous when they arent looking so sad

I won't pretend I'm a Paph expert, I've successfully grown some maudiae type Paph but sold them as they eventually take took much space when they become multigrowth. The last Paph I have is Paph spicerianum which I'll probably sell eventually as well, this thing grows like weeds!

IMO, the spots on the leaves are not too much of a worry, doesn't look like a virus at all. The brown sunken spots looks like it was shipping and handling damage that might be developing some kind of bacteria, the bottom leafs that are yellowing could be just a natural thing, but I'm afraid it's more likely rot in the crown that's accelerating the process. On your picture the crown looks likes it's a bit brownish. It's not tragic as you'll probably get one or 2 new shoots which will take over, don't forget this one is done anyway and won't flower again. Just make sure you don't rot the rhyzome and you should be fine with future growths.

I'll let the more experienced Paph growers share further insight.
