Burn or deficiency?
Ganjeeman710started grow question 4mo ago
Is this some sort of nute burn or deficiency? I had severe nitrogen toxicity 3-4 days ago. So far recovering. Since then i changed the tank out with less veg nutes and more bloom. I only started calmag last week but being careful since it has 4% nitrogen in it.. any suggestions?

Tip-burn; excess! you slowed down growth in the process of trying to go big; this time --less is more!
Buildup from a little bit too much, exceeding luxury uptake & slowly accumulating leading to excess and dead tissue in the fan leaf tips.
Even more excess being injected as u transition to flower --adding even more nutes.
**think vitamins for humans and taking too much for excellence, but instead it's making u shit your pants! xD.

too much p or too little k? leaf symptoms are not discrete. If the damage around serated tips coincides with chlorosis as it progresses, i'd say low k. if just leaf tips and margins burn and you have some chlorosis on new growth - too much p.
see how it progresses and general location then compare to a leaf chart. Unless you have info that helps further diagnose, i'd see how it progresses. this is where having a consistent feeding regimen can help. If soilless/hydro, it's incredibly easy to avoid problems consistently. No guessing about what is in the soil and how to supplement it when you provide 100% through fertilization.

Doesn’t look like a deficiency to me. Since you had N toxicity a few days ago, this is most likely just residual stress from that — damaged tissue won’t recover and new growth can look a bit pale while the plant stabilizes. I don’t see classic burn tips or clear CalMag spotting. I’d keep feeding light, avoid adding more nitrogen, keep pH in range, and just watch the new growth — if it comes in healthy, you’re fine.
