Hey fellas, long time no see haha. First this plant changed color to light green, stem is half red. After few days other plants started changing color of some leaves but not all. I think it’s Potasium or Magnesium deficiency? But not sure wich one. Stardog

What are you growing in? If its soil it looks super dense to me. How many different strains are you running in there and are you feeding each plant is own mixture based on how they are looking? 2 cents from nearly a newbie that is looking to learn more! Good luck!

Coco coir 70/30. It’s same strane only. Im feeding them all with same food. Only this one will be fed differently from others because they all looks the same but this one. And it’s just fed that’s why soil looks like that. 2 cents what?
 
You could feed all of them the same and still have one suffer a nutrient lockout. My guess is that a small lack of P or K went unnoticed locked out some calmag and thats why your necrosis is spotted like that but not rusty. A soil ph adjustment could shift the balance here.
