Looks like you might have a copper diff. Can be caused by unbalance in ph or low nutes. I would check your runoff ph and ppm. If ppm is too high it’s prob a nute lockout due to ph. If the ec and ppm are good I would say up the nutes

Ec is the electric concentration of your medium for soil ph at 6.5 would allow more of those metals into your plant. I would hit them with some cal mag and 6.5 ph water at about 200 ppm .6 ec that will allow those nutrients get to your plant.
