Does this cattleya look like it is infected with Fusarium?

Here's an updated picture of the three I got from the same vendor. It's the shriveled one.

It's a cross of a brassovola hybrid so the leaves are very different from the other two.

The pots are slotted on the sides, 3". Wishing now that I had ordered smaller pots but I think they'll be alright.

Is that bark? If so I think the pot size and medium is good for those plants. If you're using coconut coir chips just pay attention that they don't stay sopping wet all the time.

Thank you, estación. It is mostly bark. I also had some coco chunks and put it in there for more moisture retention since the heater makes the air so dry and sphagnum moss was too moisture retentive.

I use a pump sprayer (all living things brand for reptiles/amphibians) instead of soaking the pot like I do with my succulents.

I purchased the bark mix (perlite, charcoal and medium bark) from here CalWestTropical
Here's the specific stuff I bought 1/4 CF Medium Orchid Mix

It's more bark mix than coconut husks. Do you think it best if it were only the bark mix? The visible roots are white every morning so I don't think the whole pot is retaining too much moisture.

I think they're fine in that mixture. Not drying out fast is good for small Cattleyas in a small pot.

leathery looking leaves like that are dessicated....they are not getting water to the leaves...does the plant have roots? what condition are they in? if the roots are not functioning, then you need to get them growing in a hurry!

the sphag and bag method would be handy here, or at least to cover the plant with a plastic bag...the others look fine....

another suggestion would be to fill the tray half full with small gravels, and to keep the gravels moist/wet, not to the touch of the pots however! that will give you a bit more humidity as the water evaporates thru the gravel...I do that whenever I bring in a plant for show...

a large orchid business will be happy to replace that plant, but smaller growers may not have another, or will exchange for something else or a credit.....if you are really unhappy, do that!....they will want to keep your business and make you happy!
