So I have those black spots on leaves on top of the canopy of my plants. Can someone please explain what are those and how can I treat it? Also the edges of the leaves on top of the canopy are brown and crispy.

The burnt tips are a nutrition/pH issue.
The black blotches could be a fungal problem due to poor air exchange/high humidity.

Nutrition deficiency or nute solution on leaves during watering?Hi Growmies,during my monitoring routine I found some brown spots on the leaves. Not many but on some leaves the brown spots have become transparent and I can see through the leaves. Any ideas what could have caused the brown spots? Perhaps not enough CalMag? Rest looks healthy.

Weed doctors to the rescueDay 44, fb auto, my happy girl developed those dark spots at the top... Is this a Calmag deficiency? Although I'm giving her calmag every feeding. I think there are also first burnt tips. I'm about to water her tonight, what should or should not give her? Thanks for your inputs🙏
