What are these Black spots on my leaves?

[King_of_orchid_growing:)]

Oh, yeah, I'll add to the last paragraph of what I just wrote with:

...Provided you've found out what the problem is, dealt with it and changed the problem condition to a condition that the plant can grow healthily.

thanks for all the help guys! I feel optimistic about the problem. The roots are all fine and going strong. it's just that leaf that has all the spots on it. I'll keep you guys posted on how it goes.

where can I buy Thiomyl?

Try Thiomyl OSG23: Camp Lot A Noise Tropicals

[raimeiken]

ok, I got some from a local Nursery here and I mixed it with water as directed and spray some on the leaves and root system 2 days ago. Then yesterday the leaf was just getting worse and another lower leaf was getting it also. Black spots and some yellowing.

Then now I just came home and turned the lights on to see some progress and I noticed that the first infected leaf just fell off! and the other one that's infected is just getting worse. And I notice a little yellowing on some of the roots of the plant.

I'll take some pics tomorrow to show you guys what's going on.

How many time should I spray this stuff on the plant? The medication say that repeat it every 7-14 days if the problem persist. Im thinking of doing it some more right now but i wanna know what you guys think.

Sounds like the plant is still too wet. Try moving to a drier location until the rot stops. Thos spots will not go away, just stop advancing, if the Thiomyl is working. For best success, it should be used when the spots are still light green to yellow. By the time the black occurs, the tissue is dead already. Stick with the label recommendations. Extra applications won't help.

Alright I took your advice and moved it somewhere even more drier, but a little lower also, so it's a little less light.

Here's some pictures of the plant. The other leaf has fallen too. But what are these I circled on the picture? are they new growth points?

[Ross]

In the first picture (with the circles) one shows a root with a blackened tip (nothing to worry about.) The others are potential spikes. They are clearer in the second photo. I prefer to keep these under approx 1800 FCs light. Not too dim. I am sure your plant will enjoy a bit drier location, but watch the roots. They look just fine right now.

Here is what you have to look forward to:
