Rust spots and dead tips of fan leaves


Hi guys I can see the finish line and harvest is a few weeks away and one of my plants has this issue on it’s tan leaves. Basically the have rust color spots then the tips dry up and basically die. I have been trimming them off the plant and just leaving the healthy leaves and the buds. I have two questions.

What can I do to help this plant ?

Is this issue something I should be concerned with after I harvest and smoke it? Or if I cut it out is all good ?

I have been using some late stage budding nutrients that maybe helping but not sure.

Here’s some photos.

If you don’t have a growlog please answer these questions.
What strain are you growing? Is it Auto, Fem or Reg?
Are you growing Indoor or outdoor?
Are you using nutrients? Which ones? How much?

I don’t grow outdoors but those lesions on the leaves look like they’re from pests to me…
