Looks like heat stress ,if your light has a dimmer try turning it down some. If no dimmer then raise the light if possible.

What is she trying to tell me ?
Could anyone tell me why some leaves of my orange sherbet are dying ? Is it stress (the plant is in front of the fan) or cal-mag-potassium deficiency (I don’t have neither cal mag or potassium). Thanks a lot 🙏💚

Qué podría ser? Bloqueo de nutrientes, sobre fertilización? Cómo solucionarlo?
Hoy lavé raíces pensando que tuvieran un bloqueo de nutrientes. Creo no están sobre fertilizadas, pues las hojas estarían de color verde más oscuro y duras, como si fueran plásticas. Y éstas están caídas, algunas blandas y con esas puntas amarillas. Algunos tallos están morados.

Why are the sides curling up? Question not about them pointing down but only about the sides curling up and very small brown points
What is this? Sides r curling up. Day temp didn't get over 23 degrees night temp is +- 12 so I don't think she got too hot. Points bit yellow Saw this yesterday evening too, today at 1 plant a little bit. They're probably pointing down because of the low night temp so that's ok

Cupping
On the right plant in diary pic it shows slight upward cupping on the edges of a few leaves. There are a couple of others on the other side. But 95% of the leaves are fine. During my first try at LST I broke the main stem by 70%. I think this caused the cupping?

Plants deteriorating rapidly, pls help
Plants not looking good! Help! 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 .

Heat stress? (1st grow)
Hi, Here we start with the problems. The leaves are curling up (little yellow), not much. I've looked that up and it's probably heat stress? -My led lamp is at 55 cm -The plant receives 500 PPFD Also a friend told me to water it nearly 1l, if that's the case I was giving way less
