Phalaenopsis leaf problems

[camille1585]

I have a phal with exactly the same thing. Actually I had 3, but I tossed the other 2. I am hesitant to toss the remaining one because it's a Phal primary hybrid that I really like, and so far haven't been able to track down a replacement...

(Oh, and I have the same Ikea shelf as you for my orchids! I recognize it in your last photo. )

I haven't tried anything. On some plants, this only happens to one or two leaves, and new ones come out healthy. On others, even the new leaves have collapsed cells. I don't think it's bugs or a virus - I have healthy and affected plants in the same compot, coming from the same flask.

Survival of the fittest, I guess.
