Wow.......You've gotten every type of advice from too much nutrients to not enough nutrients.....high PH/low PH...high salt/low salt....add this/take away that...etc..
You seem to have covered all the angles with what you said in your last post there brother and your ladies are just getting worse......I truly and honestly wish I knew what to tell you my friend.
At this point, I would have to ask if you've considered some sort of disease or unseen root pest being the issue? I am not too big of a man to say that this is way out of my meagre knowledge base. Just hope you figure it out before you lose everything...
All my best and good luck!!!
