    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:

    Thank you all!

    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......

    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
