Hi everyone,

I have a very bad eye for recognizing problems/deficiency.

The leaf shown on the pictures are the latest growth

Are both of these cases cal-mag deficiency? or totally another problem?

case 1: little discoloration, almost like irregular and light "stains"

case 2: yellowing between vein

What kind of substrate are you using? What kind of water and fertilizers are you using? Are you under high-wattage LEDs or outdoors? Do you have an EC and pH meter?

Looks like mg and ca deficiency to me. Leaf get yellow but the veins are still green. Overall spotty looking and i see a few necrosis spots.
