Need some help. Deficiency? Light? PH?

First time post.

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.

Thanks in advance for the help.

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.

Much love

I looked up your nutrients they won't show the label, maybe you could post a pictures of your labels

it looks like a magnesium deficiency; you're feeding at a high PPM, have you taken any runoff readings recently ?

Here are the labels. Runoff readings are close to what is going in.

In varying degrees, all deficiency look the same to me.

Drop to 800ppm. Add 1-2grams per gal of epsom salt (mag sulfate)

+1

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

They look pretty good besides that, good luck!

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.
