help! Leaves curling and browning on blackberry

Need some help identifying this disease or fungus on my blackberry. Leave's edges started getting soft at first and with the sunlight they got crunchy and brown, also started to curl up. Check the pics, it's my first time with blackberries so I don't know what to do.

I won't say it's not a disease, but my first impression from the pictures is it could be symptoms of over fertilizing.

It could be, if that's the case what should I do to correct it?

The only thing I know to do with container plants that have been over fertilized is to flush them with water.

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).

Turns out it was overfertilizing. Since I took the blueberry out of the old soil and repotted with new soil it's alive again and with lots of new growth. I ended up taking the blackberry to my garden and it's also doing better. I'm getting new side shoots where I cut the diying leaves and it countinues to grow quite nice now.

I cut off all the leaves of the blueberry and all dying leaves of the blackberry. I'm gonna stick with organic only fertilizers, any tip for keeping the ph low for the blueberry? Coffe works?

Pour vinegar to the soil to lower its pH level
