Grape leaf drop hints at root, trunk issues

Question: I am having a serious problem with my grapevine. It seems to have stopped growing and is losing leaves. I used a lot of bone meal on the plants, and I am wondering if I have over-fertilized it? The ground is never dry; the flower bed it’s in is on the same drippers as prior years.
