The coffee-blood pressure link is poorly understood but is generally transitory if it affects you at all. The advice on this Mayo clinic piece is straightforward: See if it affects you, then decide what to do.

Salt is another one where the BP link is somewhat unclear. Yeah too much salt is not a positive as it causes you to retain water and that raises BP but too little salt is also bad. And your system is pretty much self-regulating. Salt was demonized in the day but now it's much less so.
Too little potassium is a common problem that goes undiagnosed.
I have high BP, been taking meds since I was younger than you are now, turned out that salt, alcohol, nicotine and caffeine weren't the problem, they were all eliminated for periods of time and the high BP remained, it's called "Essential Hypertension" which means they don't have a clue, I just have high BP. So now I do what I do and take the meds and I'm fine. In the quest to lower my BP I lost quite a bit of weight, got more regularly active and adopted a better diet and that's all good stuff no matter how you slice it. It's one way to go at least.
