Peach melred issue.

Hi all,
I've noticed my Prunus persica Peach melred is looking a little sad. When I have inspected the stems are sticky. I've looked all over and can't see any bugs or aphids of any kind. All I can see is these notch type of things and I'm unsure if they are meant to be there or not. I have taken as many photos as I can to try to find the problem.
Thanks in advance

 

I dont think the notch type things are a pest.
Sticky leaves suggest Aphids or more likely scale insect.

Are you growing this outside or under glass.

 

Hi @pete , thanks for the reply.
It's outside in a large pot.

 

The tip problem could be fungal, but dont ask me what.

Unless the others are a real problem I wouldn't be too bothered.

 

Cheers Pete. I'll leave it be and keep my eye on it.
