I'm growing a pickling variety of cucumber. Normally they grow in very predictable "pickle" shapes. A couple of weeks ago, I notice that most were oblong and sort of hooked.
In the photo below, the one at the top is normal for these seeds. The four below are exhibiting the strange misshapen issue that I'm investigating.
In the week or two since I took the photo, the newer cucumbers don't seem to be doing this anymore.
What causes this to happen?
