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. https://global.discourse-cdn.com/growingmarijuana/original/3X/7/9/796616df368212c3afee76e0b39659e90981b1a0.jpg 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).
