I am curious about what exactly was maybe going on

Don't take this the wrong way but maybe and exactly is like saying Maybe planet Mars is exactly planet Earths Moon.

Was it outside and you had to bring it inside ?
A change between the two environments is a possibility Finding an inside home for colder months could cause problems.

Just kidding down here but I had to try again
If I'm right them that's exactly the problem but if I'm wrong then maybe it isn't.

Hah, I know. I worded it in a very idiotic way. It was kind of purposeful, but dumb, and I didn't proofread. I apologize if it's obnoxious.

No, it has been in the greenhouse without being taken inside and brought back out. But the temperatures did drop from a typical 70 degrees during the day to mid-50s and the occasional 60. Some environmental change could very well be it.

No worry found it entertaining more than obnoxious

If me I'd be more concerned about night temps as well By zone here it be inside a warmer 3 season room if mid 30's outside at night regardless of day temps.
I'm sure you may have already done this but Last time I promise<?i> maybe check other plants in the exact area ?

I've checked everything up and down. I am grateful I haven't seen the same thing spread anywhere. No mealies or scale or aphids yet this season, either, for which I'm grateful--cross my fingers. And night temps are usually about 52 or 50 with the greenhouse heaters. If we get some scary night lows, in the house for the night they'll go.

Coleen,

Could it be a fungus? Maybe rust or water damage?
I would remove the leaves and watch the watering, especially in cooler temps. Do you have air movement once the leaves get wet?

Wes, loving this snow? Yuk.lol

Mike

Yeah, I wondered about a fungus or rust. I was going to remove the leaves, but then after watching it a couple days and seeing no change, I haven't. Though I don't do overhead waterings and the leaves won't usually get wet, after waterings or after spraying neem I usually will turn a small fan on low in the greenhouse during the daytime, but air movement or lack thereof could very likely not be helping the situation.

Looks like tomorrow night will be our first night of questionable temps and a nasty windchill. Yucky weekend and time to bring some things in for the night. But, no snow here, thank God! :) You can keep your snow, Mike.

Mike: Yes if you live in New England you yah got to love the snow, it means spring is on the way.

I was kind of leaning in the fungus direction thinking the OP had also suspected fungus might be why they broke out the neem.

Not certain if Neem is the best for the plant in question but any treatment is better than no treatment.
