Damage caused by water in between dried leaves

[SouthPark]

If the damage looks just minor or superficial, benign-looking, then maybe it'll be just ok to just allow that region to dry - and everything should be ok. But - just in case, a little spray of cleary's 3336 will definitely be ok.

Definitely. Whatever works for the long-term is extremely good. I've basically just stuck to a few golden rules involving good air-circulation (air-movement) around leaves, media and roots; avoid water stagnation around leaves and roots (which is benefited by air-movement and choice of growing media); adequate light level; comfortable temperature levels.

The only other things I supply to my orchids are water, weak fertilizer (weak/monthly), cal-mag (weak/monthly). Occasionally, I may use something like Ezi-root gel or Auxinone - which I keep, which are pretty good.

I've had zero cases of rot or fungus or virus for a few decades. I don't think there's much that can be done about viruses - not much can be done about that - except to make plant 'backups' (ie. divisions - and spread them out a bit).

But I do have an arsenal of 'goodies' (fungicides etc) - just in case, of which some are used for pre-treating every orchid that arrives by post.

I have lost approximately 3 orchids in my life - due to my fault. Extremely disappointing. They were catts. This was when I was first beginning orchid growing, and didn't know about certain golden rules. This was a relatively long time ago.

But once the golden rules are known and applied - they definitely help to cut down on or even eliminate the most pressing problems - like rot.

This is a good thing. The other thing to consider is what might be happening in the problem regions. As in ----- in the greenhouse, are there any significant amounts of time where the air remains still? Eg. at night or during the day - for some number of hours.

Is the green house equipped with water-proof/water-resistant fans for moving air through the green house?

For rainy days, does water pour down onto the orchids, where - after the rains - the water remains trapped for long enough time and the unwanted activity can start up?

Also - from observations of the photos, I can't really see anything that looks nasty. Letting it just dry out might be ok, and monitor the situation closely.
