Is this anything to be concerned about on my Blackberry?

Hi all,

My Blackberry plant doesn't look too good and i'm trying to figure out why.

This, along with my other fruit plants had been over fed but since then i've not done anything with it other than to pot it into a slightly larger pot.

I've not seen any bugs, apart from thes tiny little white bugs that seem to jump if you touch them but i don't know if they are the problem.
The rest of my plants are fine, including the other fruit plants, but this one.......

Apart from getting a crick in my neck, it's difficult to judge what may be wrong with your blackberry.

I can't see the whole plant or the pot it's in.

The plant is a bit unhappy but the cause could be many things - from virus infection to nutrient imbalance to damage from sap-sucking insects.
I doubt you'll manage to pinpoint the problem - not helped by it having had a strange year due to what you've done with it.
It doesn't look like it's imminently going to die so I would just keep an eye on it.
