Too much light on Odontioda or something else?

[(..._...)]

So I purchased a Odontioda Fort Point about a month ago. I have it placed in a window where it recieves bright light all day, with a bit of full sun. I know the location is a bit bright for this plant. The plant has been there about 3 weeks, and now has a red tinge to the older growth. At first, I thought it was because the new growth is growing and has become accustomed to the higher light, but the older growth is a bit- well not sunburnt exactly- but is getting a tad too much light.

So even when I first bought the plant, this specific orchid had strange dark colouring, but tons of my oncidiums have strange markings/ discoloring that is considered normal for the ocidium type plants

Anyways, what concerned me was the fact that some areas on the back side of the older growth- the portion that does not get the bight light, has that colouring as well.
Oh, and its not rot, ists more like just a rust colouring on the leaves.

Any opinions out there?

(this is a picture of the whole plant. If it were in the window, this is the side I would be looking at, and the wondow would be behind the plant.) the next picture is of the side that gets the light.

My guess would be too warm and insufficient humidity. Move it back from the direct light, and it will likely be OK.

I also had someone on my blog suggest that it could be spider mites...
well see, it could be light, but would it even effect the side of the plant that does't get all the light?

I'd say spidermites also. Use a slight moist paper towel to wipe the leaves and see if there are any red dots on the paper towel.

red dots, or like a rust colour coming off on the paper towel?

Ughh... If it is... Im never buying from that greenhouse again! I have mealies on one of their plants, and now maybe spidermites on another...

It could be spider mites, But I believe its heat related.
Cam add a fan if you can, our weather has been pretty wild these days

The Odont alliance don't like bright light and prefer cool conditions to do well, in my experience anyway and I have over a 100 0f them, sometimes a spotting and other colouring on the old growths is genetic but can also be fungus, try spraying with a spraying oil which will get rid of mites etc, do it once and then again about a week later to kill any eggs that may be there, these things work for me. Cheers and good growing.

Well its not in super bright light, just maybe it bit more than it needs, which is why I thought it was the sun. But it is getting cool conditions.. with a fan running as well as airconditioning.

I do fan.

I hope it is a heat thing.

Oh yes.. I am going to buy 'safer's defender' today, but I also have safers 3-in-1 insecticide/ fungacide/ miticide. would that be able to be used on orchids, full stregth? (for fungus or pest)
