Hey there. I would put money on it being 3 things. Cal mag. Light stress. Or heat stress. Looks like or was a good grow anyway.

Hola. Creo que tengo el mismo problema finalizando la 4ta semana de floracion. Estoy un poco asustado porque la quema no para. Tu solucionaste este tema?
También pienso que se debe a una deficiencia de P.K. pero no estoy seguro!

Deficiency?? Excess? Neither?Grown this strain before and had the same issue.. not sure if its a CalMag deficiency entirely. pH has remained at 6.0-6.5 or so in soil and didnt show signs until recently, seemed to have worsened after just two days of only CalMag and Ro water so I bumped up the bloom nutes.

Twisted, yellow/brown tips.Hi,
My plant has shown signs of a nutrient excess throughout its complete cycle. It keeps to the tips of younger the leaves that have a tiny twist in the end. I don't think it's the light as it also affects leaves in the lower canopy. I keep on flushing but nothing changes.

White tips at the end. Brown patches. Leaves curling.
I've been feeding it 0.5L Advanced Nutrients Coco Big Buds.
The light was fairly close, at 30cm. I've raised the lights to 60cm.
It was also very humid, so I've opened the air vents .
