I see two things from those plants.
1. I think they could use some N. They are quite light green.
2. They also look to be in need of mag, which coincidentally, they need to process the N.
The yellowing between the veins, as well as the leaf cupping that is going on, are classic mag deficiency signs.
Also, mag deficiency, when left untreated, will create necrotic spots between the veins.
I'd give them some mag and N, in whatever form you prefer, but that's just what I'd do..
This is it right here I would strongly recommend this for correcting the deficiency.
