Whats the top/new growth look like. Its best to evaluate the whole plant not just deficient leaves. Looks like K+, Ca+ deficiencies in 2nd and 3rd photos. Maybe foliar burn from sprays? Could be pumping too much P+ at 6.2 pH.

That last picture the third one the veins are yellow thats Mg+ likely. One of the pics has cupping. One has the tip burn. Mg+ regulates water and evapotranspiration. Any taco or canoe leaves?

Thanks for your reply. I folio spray with none pH water Evert Day. My water out the tap is about PH 7.5. My grow is 54 plats and all the other are all green and happy. I have 6 600W HPS with nine 11 L pots under each
Happy growing

Water has never touched a single leaf of these girls.... Personally I think spraying anything on your plants is unnecessary.
