Curled leaves on phalaenopsis hybrid.
 

One leaf of my phal is twisted and curled down.
First time seeing this and I'm wondering if anyone knows what causes this.

I hope it is not something I need to worry about.

By the way, other than color streaks on flowers and dark sunken spots, anyone know how virused phals look?
I read somewhere twisting leaves of phals are virused.

Well, this phal is not something I would cry over if I lost it, but still curious.

Dive in, people! :)

By the way, the plant looks perfectly fine otherwise. No markings on the leaves, lots of good looking roots. just this one twisted leaf.

Change in temp and humidity is my guess. Happens to me a lot living in a highland desert.

This plant came like this when I bought it. I didn't like how it was curled out and down, but the flowers were nice so I bought it anyway.

So your phals do this a lot? I guess it is not a big deal other than just an aesthetic defect. lol
