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

Deficiency issue
Brown spots on one leaf, only one leaf on plant of 6 showing issues. We're about half way through week 4 and only introduced PK feeds 2 days ago, I've not added any epsom salts yet or any CalMag. Is this a PK or CalMag problem? Further info on my current diary available, thanks

Brown spots
Hi everyone, brown spots are forming in the lower middle part, fortunately only a few have this problem at the moment, can it be due to a lack of calcium?

2 out of 5 plants are showing signs of nutrient burn? Soil grow
Hi, I am seeing clear signs of nutrient burn but only on 2 out of 5 plants. I feed them organic nutrients, following the chart that was provided by BioBizz. Why are they still showing burned leaves? I watered them thoroughly until the runoff was clear. But leaves keep burning.😦

Leaf necrosis
What's going on with mk Ultra? It gets Neem every 2-3 days, and I have tried to keep pH down to 6. This has been going on since I got the clone, and it continues to happen. The pink kush (last pic) has a few similar spots. Lights are 50cm above.

Brown spots on the Gold Leaf?
Brown spots with light yellowing. Possibly calcium deficiency? This is only happening on the Gold Leaf. Neither of the GDPs are showing these signs. This has happened over the last 2-3 days.
