Can anyone help identify these brown spots on my wisteria?
As per the title. I bought a wisteria (American I think, amethyst falls) and repotted it into a larger container. It has new growth but I’m seeing a lot of the leaves curl, go brown at the tips and some of them are displaying this speckled look. Any tips would be appreciated as I’m a complete novice. I’ve been watering once a week when it’s dry weather and feeding every week or two with a generic food. I’ve only had the plant for 4 weeks.
