EE disease... need ID

Hi all, today I noticed several leaves on my EE's growing in one area that look like the picture below. I was concerned about virus at first, but not all leaves are affected, plus some of these are in the ground and others are growing in pots with other plants, and all have some leaves that are affected, but no spots on any of the other plants (not EE's) growing nearby. Another EE growing only 10 feet or so away in my pond is unaffected.

Not all of the spots go through the entire leaf, but some do.

Any info would be appreciated.

Another pic of an older and more beat up leaf with the same problem.

It might be worth mentioning that this came on very suddenly; these were ok as of mid last week.

Also it's gotten cold at night as well, night temps in the 40's and low humidity suddenly from what it had been, which was the 70's/upper 60's at night with a lot of humidity.

looks serious. never seen that before

i dont know,but did you feed them lately?a few months ago someone told me they love food,well i fed them and burnt several i had.just a thought i had ,that maybe you had fed these and burnt them.ill not feed maine anymore.lol

Looks like chemical damage or burned spots where you watered and the sun came out before they were dry. It could also be a fungus. I would cut off all the damaged leaves(wash the knife or scissors with alcohol between plants just in case), make sure the soil moisture is just right(not bone dry, but not a swamp either) and they should recover. If the new growth is spotted, it's time to get out a fungicide like Daconil. You will have to add something to make the fungicide stick to the leaf, a teeny squirt of a mild dish soap should do the trick.

Thanks for the info everyone:-) I haven't fertilized in a few weeks now in anticipation of winter, but the spots to look like burns of some kind now that it was mentioned.

I have plenty of fungicide, but I like to know for sure before I use it.

I had already gone ahead and cut the affected leaves off, and I'll keep an eye on the new growth.

Indigo, the ears are so sensitive to chemicals and sunburn and windburn so it could be any number of things that damaged them. I agree, better to be sure what's wrong before you start spraying chemicals. My ears were so pretty, then we had that cool spell with hard winds, now they look pretty battered but the new growth is good.

Susie, do you ever wish you were back in Tennessee where it isn't quite as windy? I know your winters have to be better, but I sure do get tired of wind.

Brugie, I haven't decided if the warm winters make up for the wind but I sure am enjoying not having to bring things inside!
