Sunflowers curling leaves

[Phaedra]

So the flower leaves are all curled too 😳 I won't be saving any seeds from these. The chickens can have them.

My first sunflowers had all curled leaves, but the flowers are pretty normal.

I still can't find a reason for this odd curling in this cluster of sunflowers. Seeds from the same packet that were planted in a different part of the garden are growing just fine. Just this section is causing the odd curling.
