Never easy, I have 3 books and have found that the picture for say magnesium deficency in one looks identical to the iron deficency in another.

Add to which on one of my raspberries one cane looks great the one next to it would appear to be magnesium deficient yet they are on the same root unit and 1/2 inch apart.

You could get a good idea from the type of soil you are in, clay, sand, acid (peaty) or whatever. Then find out what these are charactoristically deficent in and then, if necessary, compensate for that.

The third picture could easily be too dry, raspberries do not like getting dry and that lack of water means no mineral take up. A deep mulch on a raspberry bed is close to essential. They could show a mineral deficency because insufficent moisture to take up minerals.

Are these on canes that have fruited? If so they all look a bit ropey now as the canes die back and the leaves fall.

Autumn come too soon..........premature defoliation?
