Shrivelled and crispy branches, pest or disease ?

[Struth]

Outdoor grow, a couple branches are shrivelling! And crispy. The rest of her is fine but afraid it will take over the whole plant. Its probably just about to go into flower. I don't know if this is a deficiency of some kind or a disease? Any help appreciated, cheers. Edited January 31, 2021 by Struth

Could be a few things , 1 things for sure its killing them

Check for bugs, borers , ants or termites

Could be stem or root rot

 

You need to find cause asap , it will spread

Thanks for the reply. So no signs of any insects or stem rot. Perhaps root rot? Not sure how to identify that.

Also can this be spread to neighbouring plants?
