Leaves turning black and shriveling only on isolated branches

[Jonny_420]

This is an outdoor grow Acapulco gold photoperiod growing healthy for the most part.

maybe a little late for flowering but I am growing in Vancouver bc?

I just came back from a vacation to notice a few branches have this weird black colour and small curling leaves, anyone have any experience with this?

Also a few larger leaves seem to be yellow veined with brown spots

Thanks In advance

Check with some more experienced growers first, but that looks like something that needs to be removed before it spreads to the rest of your plant. Looks like some sort of necrosis going on.

It’s just on one or two branches I’m thinking it may have been a nutrient burn, I had some inexperienced people taking care of it the last few weeks, fingers crossed it’s nothing too serious
