Brown spots

Hello team! I've got brown spots on my leaves. I've used my microscope and can't see bugs. I've been feeding about half neuts (2.5ml/L canna vega) ph is 6.5. In soil. Can't think of anything I've done.

I had a look at your diary. I'd say this might be a air circulation issue or water sitting on the leaves after watering, or leaves touching the soil. It looks like a disease more than a nutrient deficiency. Is it isolated on the lower leaves? or is it evenly distributed through the plant? I'd say its some kind of rot and I'd clip the infected leaves off and monitor to see if it spreads. If it does then it could be a soil borne disease or nutrient issue. If it doesn't then problem solved.

I think you potentially have a calcium deficiency. Try adding a little more cal mag on your next feed. Good luck bro 💪
