Can't figure this one out. I know its hard to determine unless you know everything that is going on so here is some info. Growing in Coco with perlite, using Mills nutrients Vitamize, A, B, start R and a little additional Calmag. PPM = 1,100 - 1,200. Using Mammoth P active microbial, hygrozyme, URB and occasional hi-brix molasses to feed the micros. PH'ed to 6.0, Using full spectrum led lights set at about 170 umol m s. Temp is 72 deg and RH at 65%.
Not all the plants have this issue...which doesn't make sense. The plants are all the same strain cut from the same mother plant.
Im a new grower, so take my opinion with little weight. It looks like a deficiency more than a toxicity. I would guess it a calmag deficiency. I had similar symptoms on a plant and solved it with calmag increase. I have also herd that its very difficult to get calmag toxicity in coco coir. So with my little experience, I would increase the calmag.

Ok writing this cause i see this issue often and rather have a thread to link than explain this each time. This is not my work but a collection of info from many members here and I have put into practice myself. So first off COCO is NOT soil. For best results we want to keep it saturated...

If that were my plant I would mix one gram of Epsom salts to 1 gallon of water and spray it two days in a row to stop that magnesium deficiency quickly
Here is an update after the Epsom salt spray (see Pic). I know it takes some time for the color to come back but overall the plant looks much healthier and color seems to be coming back slowly.
