Monmouthshire, United Kingdom

I have 2 blueberry bushes. One has leaves that are curling with bright yellow powder on them, and the other is covered in berries, but the size of tiny ball bearings which are not ripening! Help! I've given 'Miracle Grow' and 'Miracle Grow Ericaceous' feed. the one with the yellow powder is soooooooo thirsty, I have to soak it every evening.
