You are experiencing progressive potassium deficiency. Light nitrogen and heavy potassium are phosphorus in flowering. Good luck🌱

Hey everyone, I've had these brown spots on the old leaves of my little plants for a few days now. In the weeks before, I fertilized, but only with 1 ml of BioGrow, 1 ml of BioBloom & 2 ml of CalMag from BioBizz — I think it's more of a deficiency. Thanks a lot for your tips!

Why leaves brown? (urgent)
Some leaves turn brown as in the photo. Leaves in the middle turn brown first, then bottom leaves. Now I try making larger lamp-to-plant distance and feeding less nutrients, but no good sign appears. Other conditions are stated in my diary. Why do you think it is?

brown spots on older leaves
The brown spots are appearing more prominently on the older leaves. Overall, the color of the leaves is rather light green compared to other grow diaries. What could I do to fix the deficiency?

My Blue Cheese Auto isn't doing so great... In my opinion, it shows signs of clawing and root rot, I need tips. It's in a 19L pot, I know it's a bit big. I have clay pebbles at the bottom and then mixed coco with all mix and let it grow in coco on top.
