Possibly the early signs of a calcium deficiency. Not a magnesium deficiency. What are you growing in? Soil or coco or hydro? What kind of water? Tap or Reverse Osmosis or Distilled or Well Water? What kind of nutrients you using? And are you adding any additional cal mag supplements? Some basic questions we need to know in order to help you more.

Hello!
Good to hear from someone, thank you!
I am growing in soil and I feed with tap water and biobizz nutrients. I didn't add any cal mag supplements.

If it spreads to other leaves or gets worse I'd say try to find a cal mag supplement and try that at 80ppm. If that dont work tey flushing your soil with phd water. Are you adjusting your ph between 6 and 7 every watering and feeding? If not you shud be or that can cause lockouts. How often are you feeding nutes? If your feeding every time you should just do phd water in between feedings or could cause a lockout. If the ph is off it could also get locked out of nutrients the plant needs to thrive.
