.... that high of pH can start to put the squeeze on some nutes,...
... but that doesn't affect Mg or Ca at all,... that dolomite, even at the top, will still affect Ca/Mg content, and especially pH, as you're seeing now,.. I still think this is an excess issue, not to the point of toxicity, but certainly interfering with uptakes,...
... OF is leaf direct, so not influenced by soil, and no overt toxicity symptoms,...light distance is fine,... EWC too,...air flow not an issue, but maybe you're letting it dry too much,... the herd, roots and overall chemistry all hate dry,and rehydrating unevenly can happen! heft the pots, do they feel like they did when you first set them up and well moistened? Wetting agents can help with this, sometimes dry patches become a bit hydrophobic an water runs around it rather than through,...
... the two pale ones, I'd swear that's S defc.,... only one that pales the whole plant like that tops generally worst as S is immobile,... not sure if it related to the excess Ca/Mg, or just plain not enough,... epsom foliar might help,...
...AH! just saw new pics,.. I think that edge streaky yellowing is Zn defc. kicking in, from the high pH,... time to start adjusting your water pH mate! ...use citric acid, canning stuff is fine,.. low 6's at first, and see how that works for a few waterings,... dealing with immobile nute defc.s is a bit of a struggle, foliar is best, but you need the right supp' for this, more nutes aren't the answer here,... adjusting the pH is critical to making it available again,...
