brown spots on orchid leaves please help

[WhiteRabbit]

I moved this thread to the "Pests and Diseases" forum with the hope that you may get more responses ...

If it's quite cold out, I'd move it away from the window.

Perhaps with the holiday approaching, members may have less time for OB than usual.

I think it is leaf edema, when the temps are cool and roots absorb more water than the leaves can transpire. It creates marks on the leaves.

Hello Alinka I see your one message was moved to a different location on the forum hope this helps. I'll be coming back later to see if you found an answer to your orchid leave problem. Good Luck, Michael

I'm not sure 100% as the pics are (sorry) too blurry to be definitive. Purple spots are a sign of good lightning, the upper limit. Depending of the species or the ancestors of the hybrid, the spots can be on top, bottom, along the middle, all over the leaf, along the edge, in tiny, large, regular or randomly shaped spots. On some species it's even solid under the leaf.

Now, I'd be curious to see more clearly the top spots of the top leaf. Some look very regular, and a bit too circular…

Also, I'd like to see more clearly the under leaf like on 20141120_120802.jpg. There's things I can't decide if it's nothing or nasty.
