Brown sport on same leaves
Mr_Heisenbergstarted grow question 2y ago
I found brown spots on some leaves. The plant is in the 7th week with flowers.
Could it be septoria? Or Magnesium deficiency?

Hello Mr_Heisenberg, this is a very early stage calcium deficiency. If your pH value is 6.8 like you mentioned in your diary then the problem is that you do not provide a cal-mag supplement.
But when I look at your plant overal I can also see a small nutrient burn and too much Nitrogen.
My advice would be to cut down the nutrients to 75% from what you are giving now and add a cal-mag supplement.
Happy Growing buddy! 💚

Have you flushed your plant? I read that you were struggling with nutrient burn. Apparently, I would tend to overwater, which is a common problem after flushing the substrate.
