best way to approach this cal mag deficiency

[LBH]

Maybe I'm crazy but I'm not seeing a cal/mag def at all, if anything, they look hungry, especially in the N area.

I've never grown in coco but I did stay at a Holiday Inn last night.

If your not feeding cal mag and your plants start showing signs of calcium or magnesium and there lush green and are clawing from to much nitrogen than you might be a candidate for cal mag, it was apparent to me that a higher ec of my base ferts was not going to fix anything.
