Yellow spots on leaves

Hi, I've noticed these spots on the leaves, does anyone know what they are please? Leaf Septoria? I hope not. It's a soil culture under leds, I used Biobizz products (Bio grow, bio bloom, top max) with biobizz calmag, I adjusted the ph to 6.5 with biobizz bio down. Thank you,

I suspect there is a calcium deficiency. I would lower the pH to around 6.2 and maintain CalMag at 1.5 to 2.0 ml per liter with every watering

Hey! Leaf Septoria typically shows as yellow or brown spots with dark borders, often starting on older leaves. Since you’re growing under LEDs with Biobizz products and a controlled pH, fungal issues like Septoria are less common indoors but not impossible if humidity or airflow is off. Also, nutrient imbalances or pests can cause spots too
