I have 15 boysenberry plants. The leaves are curling on one of them, but otherwise it appears healthy. This particular plant gets quite a bit more water than the rest because of where it’s located. Could the leaf curl be caused by overwatering? The last picture shows healthy leaves for comparison.

Herbicide damage causes a “drawstring bag” type of leaf curling, particularly dicamba.
Have you used any manure based compost or hay? That could possibly be Grazon damage. https://youtu.be/A6pI4KA47kI?si=7pA7bRDsnO9DQfgZ
