Se está espigando?

Hola. Seguramente que tienes luz muy lejos si se suve para buscarlo. Me ponia 40-45 sm bajo de la luz y depende de Co2 me ponia la luz. Tengo una planta a la misma edad de suya con co2 1200 me pongo 800-900 ppfd. Os deseo lo mejor con todas sus plantas.😎

Yeah, it clearly stretched too much. Increase light but make sure you don't go too far the other way. Should see 'some' spacing of nodes as they form going forward. take note of timing and ramp up of light... devise a better plan for the next seedling. revise / repeat until your procedure gives you consistent results. A consistent climate helps, too. You could see seasonal differences, otherwise.

Yes, definitely. As already mentioned, you could add more soil to the pot to help support and stabilize the stem. This will encourage stronger root development and reduce the risk of the seedling bending or falling over. I also recommend using an app like Photone to measure your light levels, including DLI and PPFD. The app is very beginner-friendly, easy to understand, and can help you make sure nexr plants receive the right amount of light throughout its growth stages.

Yes, definitely. Good move lowering the light! You could add some more soil to the pot, about 2cm, to help support the stretched stem. As long as you don't keep it too wet and only have the soil moist, there should be no problems caused by adding the soil layer.
