Are they sick or normal??

Hi everyone! I have recently acquired a few orchids for my collection, and I realized that there are a lot of spots on their leaves and stems.

The first four pictures are on the Dimeranda stenopetala, white to yellow marks on the tip of leaves, groups of black spots on the underside of a few leaves, and black spots on stem. I saw a few ants crawling on it today (I reported it as soon as it arrived, it was potted in sphagnum moss and oasis, I tried my best removing everything and reported it in medium and fine bark chips with charcoal and perlite)

The fifth and sixth pictures are on the den. unicum, there are a few light indents on the leaves making them look wavy, they are not mushy or soft, hope you guys see it and get what I am telling (I am not talking about the white spots from the spray that I used on them and I did not repot it).

The last picture is den. pierardii, the stems have many purplish spots and smooth in texture. I did not repot this plant.

Would everyone please help me identify what they are, good or bad, and how to treat them! Thanks a lot!!

I can't help you out on anything other than the den pierardii (or aka aphyllum). Did you by any chance get that from hausermann's? I only ask because that's the exact same way mine looked from them and I was panicking about scale and other bugs that could have caused the damage. But, well... mine looks pretty alright... lol I believe it's actually from being grown in high ligh conditions which these guys love. They rapidly turn into beautiful monsters if grown properly. So at least that one is ok

Hi Sara! Thanks for responding!! You are very correct, it is from Hausermann's!! And wow, your pierardii is stunning!! I am still trying to figure out if I should mount it up, I am afraid of breaking it roots... but your mounted monster looks amazing and makes me wanna do it!! 😍😍

If you think you can manage a mounted orchid in your growing conditions, this is a perfect one to start with. Otherwise, they look just as stunning drooping over the sides of a pot. just make sure you hang or place them in a way for the pseudobulbs hang freely and not rest on a shelf.
Edit: I forgot to add-- If you do plan on mounting it and worried about breaking the roots, you could always wait until it puts out new growth next spring

Dimeranda stenopetala looks like mine from Hausermann's. The spots never spread and the plant has thrived.
