TGB, what's up? So, you're in a big square smarty, what kinda soil? Are you running a no-nute's super soil base or something? In any case, a pH reading in there would be very helpful,.. have you scored that Accurate 8 pH probe I've been barking about yet?
Cannot be beat brudda, and in this situation, it's the only thing that will work,... Since it's teas only though, my thinking is it's lack-of defc.'s kicking in,.. lowers do look a lot like P defc., with the broad wasting patches, but others are in play for sure,.. that pale top looks like it could be S, maybe Zn, Mn,... Can you get some Earth Juice Microblast? This stuff is awesome, full micro-nute coverage, much of it compounded with sulfates, so that base gets covered too,... As you know, the pH deal is to make sure that's not the problem, and adding more nutes will make matters potentially worse,...doesn't seem likely given things, but never rule it out! meantime, some epsoms will give the S (if that's what that paleness is, could be something else, or a combo defc. thing too),.. micro's, there no work-around, you need real foods, not teas,.. P can get in that way though,... got bat-poops? Or organic bottled stuff? Roots HPK is a nice product, liquid poops basically,...
what's with the hay and weeds?
