Damage on Phalaenopsis leafs - what could it be and how to cure it?

[RosieC]

I'm just wondering if everyone is looking at the wrong pictures.

The first in that album link are a very dehydrated orchid as everyone has commented. But your comments are about marks on the leaves and that matches the pictures near end of the album of pictures.

Can you let us know which of the pictures are for this problem or are they all relating to the problem?

I'm afraid if it's the ones at the bottom I've no idea what might have caused that. Hopefully someone else may.

Good point Rosie. I was looking at the top photos because I was assuming that they were the most recent, and I didn't even scroll down that far, and didn't even see the ones at the bottom!

Well, at first glance the damage on the leaves in lower pictures looks like it could be caused by thrips. I had some on my plants a while back and they produced similar marks. Spraying with a pesticide should help (maybe someone else can chime in and suggest one since I have not had much success with them in past). Be sure to get the undersides on the leaves as well since that is where the insects reside. If memory serves they look like tiny black flecks. They have a sucking mouthpart to drain the "juices" from the leaf, hence the collapsed portion where they have been feeding.

And just to agree with everyone else, you should water more because the plants in the top photos are badly dehydrated. you said somewhere that you water every 3-4 days which should be enough even with low humidity, did you soak the bark before potting?
