Oh bollocks...
I'd say something (such as vine weevil) has munched some root tips which is why it is specific limbs are affected rather than the whole plant, so do a soil drench to kill the fkers then flush with H2O2/enzyme to break them down
Chop it back completely, she will be painful to look at for a while, but these plants are amazing at bouncing back
If it were me, I'd have them out of the pots and change the soil anyway, picking the fuckers out as I go
All is not lost Trala!
