That should help you in the future with identifying a disease.
I have to concur with James, that looks like far to much fertilizer.
The choices for correcting that situation are multiple flushing with water or repotting with new soil (in a larger container).

I think your blackberry looks fine. The blueberry is experiencing chlorosis, which being blueberry I suspect is from an iron deficiency. Blueberries need iron, moreso than most other edibles. Blueberries like a soil with an acidic pH, 5.5 is a safe number to target. Iron becomes less available as a soils pH gets less acidic, or goes up closer to neutral. Adding amendments to acidify a soil takes time for it to work, sometimes a year or more. What kind of soil is it planted in?
