I need a confirmation

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?
