Do you know what's wrong with these leaves?

Using AN 3-part, B-52, Liquid Karma, Cal-Mag (maybe not enough???) I'm using RO water, but I'm only adding half of what is suggested because the label says if I'm using AN 3-part I won't need cal/mag (even when using RO water). I suspect this is incorrect, and any advice would be appreciated.

Running RDWC using LED's. Temp/RH/PH all good.

Check out the picts:

I would say your lighting, but then again I am no expert, just an old schooler trying to learn the ways of the newer younger generation......

what is your ppm level? what is you ph? u doing dwc? how is your root looking?

looks like a Mg def to me, my plant is goin through the same thing. i still need to figure out a way to fix it tho

My last run in soil had the same problem. Crinkled and crunchy leaves. I'm pretty sure it's mag def but not 100%. When I saw the problem in my soil grow I thought it was over watering so I backed off on the water and it seemed to recede. But obv yours is hydro so

I had simliar problem before. at the end i found out my ph meter are f up. u using co2? try to flush it and only use 3 part and cal mag
