Yellow leaves who die off...

Hey buddy! Do you check the pH?? If the pH isn't in the optimal range, the plant might show yellow leaves that eventually fall off over time. The stems have a purple color, which is a symptom of a deficiency.

She’s just hungry

Yep, lack of nutrients. She is cannabilizing herself due to a lack of nutrition. That is, taking goodness from the older leaves to feed the growing parts and this is why the older leaves are dying. Increase you feeding slightly, but don't over do it and don't try to fix it all at once. Gently does it.........

Yup. A diary helps. But, overall it looks like core NPK issues. As its early in the stages. So, more often than not. It's NPK def. Up your feed. Can't c what u giving so. Anyways, good luck.

Need more pictures of the stems and dairy
