Something's Up With My Orchid's Leaves

Hello, I don't have my glasses right now, but mostly sure it is fungal, some of this things spread with splashing water too, so I would just be careful to not spread it, the plant looks a bit dehydrated to me. But I'm used to see them in greenhouses or terrariums lately so much, that maybe I'm just paranoid about its wrinkles.
Do you feed it?
When was it last repot?
How often you water it?

I wouldn't panic, doesn't look like a virus, so all cool, just avoid water over the leafs and let dry a bit between waters, ensure that theirs normal airflow, not a hurricane thought... Just wind. And don't move them too much, I have had some of my plants get pretty sad when I got moving them around too much.

Hope to hear your answers soon and that they plants are better.

 

That is a systemic infection; a topical treatment won't touch it.

I would suggest a copper treatment (copper sulfate, as in Phyton 27), or Thiomyl (aka Clearys 3336) if you want to go the chemical route, or Inocucor Garden Solution, if you prefer a biological cure and boost.

 

Frankly, while I usually do cut off such parts at the first indication, I think it's too wide spread at this point. I agree with Wolf that it's likely fungal, and is probably throughout the growing area, not just in the plants themselves. In addition to treating the plants, you should probably disinfect the entire growing area, as well. My "go to" product is Biosafe Disease Control, although if you don't have any particularly sensitive plants, Physan is a great product, as well.

Such fungi are ubiquitous, and I'd guess that there's something about your particular growing environment and watering technique that has allowed them to flourish, but if you jump on them now, and do a periodic "cleansing treatment" with the disinfectant, it'll soon be in your past.

 

Hello!
(Thank you for the help!)
You are welcome
(I haven't repotted it since I first planted it, which was about a month ago.)
You disinfect the media?
(I do give it plant food whenever I water it and try to water it once or twice a week.)
I don't know your plant food type, but I only fertilize once a week, you know some people say... Weekly weakly or something creepy like that, maybe is not the source of the problem, but maybe is a lot of food!
(Do you think it's something I should cut off just in case? Or should I just leave as is? I've thought about spraying it a bit with hydrogen peroxide but I'm not too sure.)
I have spray stuff with medical alcohol the common one in the pharmacy, 50/50 with water and it didn't went bad, but it was useless. I have only one time cut affected leaf parts and it didn't work. I don't really know what to say there, I just focus on try to heal the whole plant, you know sometimes maybe things are not really local, more like general, but with fungus one never knows where it is...
(Thank you again! I'll definitely try to keep them in one spot from now on.)
Very welcome, I always try to help others, you know, if everyone helps each other, everything would be beautiful.
Good luck and hope everything goes well, keep us updated.

 

Hey! How is your orchid doing today?
