Dry and crispy at ends

If anything besides ph it would be a little low on potassium as she went into flower. Not a cal/mg shortage. If the tips were yellow first before turning brown, then it just needed a little more k when they were turning to flower. Cheers

Hi growmie looks as though she has calcium deficiency nothing some cal.mag won't fix go in at a low dose to start and see how see does . hope this helps and answers your question x 🙏

Hi, looks like a little nutrient burn coupled with high heat and wind burn. I push my plants to get a touch of burn—- I wouldn’t worry too much.

Nitrogen toxicity makes leaves claw down., so you know its not that. So it is likely a ph issue. Check your runoff soils ph and ec levels. Can't say what you should be at., don't know how your growing. Cheers
