From what I can see.
She's in need of K.
This should help you and then you can look up your fix by checking out exactly what the issue is by comparing it to this chart.

As for the brown lines going up the stem. That's clearly just a mutation that is a by product of K shortages. Never seen it. But you are in need of feed by friend.
Good luck.

Honestly, I've never seen anything like what you've circled on the right hand side... but the rest of it looks like she's needing a lot more potassium... I'd start giving her a PK boost.. you might also give her a very small dose of BioGrow - she's looking very yellow there... Plants in flower don't require a lot of nitrogen - certainly not at the level they need it in veg - but they do need SOME....
Good luck!

There seems to be some evidence of a calcium deficiency, a well as a lack of other major nutrients in general (under fed).

Browning of leaves, heat burn or pests?Plants are showing signs of browning, and other weirds leaf markings, kind of grey-ish not too pronounced. It's been very hot and sunny here for 5 days, temps reaching above 37°. I left them in the sun during this period, is it heat stress? Otherwise growing nicely.Leaves. Edges burnt

Should I harvest early? Light stress, leaves browned and dried out, buds are all amber pistilsSo this plant has been suffering from light stress for the past two weeks or so. I have removed all the dry and brown leaves. The buds still seem fine-ish. Should I just give her the chop early and save what I can? She's been flowering for some 6 weeks.Buds. Not fattening

I think my plants are suffering a Phosphorus deficiency due to lockout due to low ph of soil. My first flush only helped for a while. As soon as the medium gets too dry damage resumes. I went to check on them yesterday and the amount of damage they took in 24 hours was pretty bad5 years ago
