Leaf tips curling up are an indication of LED burn. I’d suggest trying to raise your LED lights.

Curled up leaves on day 7
I started a plant ten days ago and from the 7th day some leaves started curling upwards. I flushed the soil one day before planting the sprout and watered it again on day 9. I use the Fecida 600 lamp 16/8 day/night. Does someone know what could cause the curling of the leaves?

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.

Otherwise healthy leaf curling in on itself at top of plant
Anything to be concerned about? This is a plant that has had a history of yellowing leaves due to I think nutrient deficiency. New leaves are coming in light/dark green. Maybe caused by being too close to the lights? (It is my shortest plant with about 1 ft distance)

Leaves turning yellow from the bottom up
My older plants leaves are turning yellow from the bottom up. Its probably a nitrogen deficiency I think, I read that its common for plants in late flower but this one just shot its first pistils. What would be the smartest thing to do to combat this? Thx Its only on 4 leaves rn

Overwatering?
Can anyone confirm that this curling up is due to overwatering? I don't see any yellow leaves that would indicate overheating. But I read it could also be a nitrogen defeciency? One pic is upside down, I wasn't stoned taking the pic, honest 👀

Hey guys. Leaves not curling upwards as such but I'm getting some leaf tips that seem to be reaching upwards slightly. Does this mean I need to up her cal and mag intake? I read somewhere if the leaf tips are starting to "pray" towards the light it could be a cal/mag def?

Necrotic spots
The last day or two I’ve had a bunch of necrotic spots pop up on the lower 3 sets of fan leaves. She is at node #5 now and starting to put out pistils. Is this phosphorus deficiency? I changed the res as it was close to a week anyways. Thanks all for the help. Happy Growing!

Slight Curling
What to do about the slight curling happening to 2 of my plants? Is it burn from temp/humidity spikes. I had been having issues so I since got a humidity/monitor controller. My lights were very close too so moved them to the recommended distance per the instructions.
