@VetSmoke85 I am no good at specific deficiencies but I have suspicions about the decline of the plant if the roots have been subject to excess water over a sufficient period. I didn't learn this lesson last year when I mistakenly overwatered a plant that had been looking great, by giving multiple waterings in response to wilting leaves in the hot sun, for it to then start looking like nutrient issues when the soil should have been good nutrient wise.
This year for me, I trained out bigger canopies in the hot sun and repeated the mistake, the lesson then finally went into my grey matter and I realised my error. And my feeling now is, if the roots are subject to excess water for too long the plant starts looking like it's got nutrient issues, a red herring when the damage has been done by excess water. In your case I have no idea, but I just mention it because of what @greenvein pointed out, in case it relates. The plant I recently buggered looked very bad nutrient wise when it shouldn't have, I chopped off most the damaged stems and now it shows recovery, and has grown new stems and the new growth is all a nice green, which I conclude means the soil is actually fine, that there was actually not a direct nutrient issue, but one bought on by stressing the plant's roots with overwatering. Good luck!
To me this is gold and to point out the reverse psychology of how we manipulate plants for maximum fruit. For example why lollypoping is so effective.. I grow absolute jungles so I know my roots will mimic top growth then cut it all back for flower, now my roots can handle double my top growth.. uptake is maximised, fruits can peak and it will take alot more to stress the plant.
On the flip side if you was to damage your roots or cut them in half they can only supply the top with half of what they need so although back in a healthy zone it will still have to get more nutrition then the roots can supply from somewhere.
That's what I took from stingers post lol maybe extreme as my brain can be but definitely a Plants balance of life.
