24 hours light is not needed. 20/4 tops or 18/6. Living things like rest. Clawing is usually a nitrogen toxicity sign. I am unsure how bright you have your light. It may be too much light. In vegging a less intense light promotes growth encouraging the plant to grow to catch the available light. There is a limit of course.

Seedling with leaves struggling to open and slighly curved upwardsI'm seedling two Super Lemon Haze Auto, but one of them is struggling to open their leaves. They are slightly curved upwards and without the shape of a normal leave. The other plant is growing fine, and I'm watering them with the same nutrients. Any tips on what can be happening?

Brown spotsWhat is this? It's affecting newer growth, first or second set of fan leaves off thee top of the colas. Also, this drooping, is this stress from the light? This is the center of my tent, and would appear to only affect tallest colas of this plant.

Curled down leavesShould I be concerned about these curled down leaves? there are only a few per plant and they look good otherwise. I wanted to flip them to flower but wondering if I need to readjust my nutes and give them more time? Last 5 pics are of the curled leaves.

Leaves curling down, ClawsI got claws on 1 of my plants, leaves are curling down. I think it's nitrogen toxicity but im not sure since they can handle a lot of nitrogen during veggie right?
I already flushed to be sure.
I would like to know what's your diagnose and how to handle it?

Leaves drooping after transplantMy one plant has been starting to droop and the leaves are wilting down a day after transplant. I know this can happen from transplanting as the plant is going through additional stress but is this what’s going on? If not, any ideas? See photos week 9. Thanks!4 years ago

Blätter welk verdrehtDie Blätter wirken welk bzw. verdreht. Sie sind heute den ersten Tag im 12/12 Modus mit anderem Licht. Was könnte es sein? Zu wenig Wasser Zuviel Dünger kann ich ausschließen sie bekommen noch fast die gleiche Menge Wachstum wie zuvor. Und davon auch weniger als gefordert
