In one of those images, it looked like a leaf-rolling insect had rolled some leaves (looked like a bit of webbing).
Wouldn't be the main reason for your post, but that's what the image looked like.
Had any weather extremes there, like a dramatically quick increase of hot weather with very little transition from cooler weather to hotter weather?
In the second batch of blemish images, some leaves like that on plants are not too bad, and can occur from moisture sitting on leaves at night from dew, rain or irrigation. Do the trees get moist at night? |
