Leaf Problems

[Ghosthunt64]

Sorry, but until I get some amount of experience, you are going to see these posts from me a lot.

The following problems only occur on older leaves, so I'm not even sure if something is wrong. New growths and leaves completely healthy.

1. Oncidium Sharry Baby 'Sweet Fragrance' dying from tips, yellow halo.



2.Maxillariella (Maxillaria) Tenuifola leaves dying from tips, strange spots.




3. Multifloral Paphiopedilum Leaves with orange spots. No halo.

Rothschildianum seedling:


Blooming size Saint Swithin.

Sorry, I don't know the answers, but I have exactly same brown patch in the leaf folding of my St. Swithin and would be interested to see if somebody knows what it is.

I wouldn't worry about the Sharry Baby, it looks like it may have had fertilizer burn. If it bothers you just snip the end off and dust with cinnamon.
The other spots look like cold water spots that turned into a bacterial/fungal infection. You can leave them or dose with some regular brown Listerine.
