Black Raspberry Not Looking Good After Topping

Question

Hello and thank you for this wonderful service. I recently headed my two black raspberry plants, each of the long canes. 1 plant looks great and is beginning to develop side lateral branches. The other one just seems to have stopped production, the leaf color has faded to almost yellow, leaves are a little brittle and less vibrant, and canes turned purple. Is there anything I can do to help restore them to vibrancy? Thanks!

I would recommend, first, testing pH and nutrient levels. I suspect a pH swing which will lock out certain nutrients.

Amend according to your testing.
