Overwatering?

The one plants looks a bit overwatered but the others are mostly happy. Not all plants drink the same and should water based off of needs of the plant. If it dry give it some and water the entire medium. allow it to dry out a bit before adding more.

Looking at your pictures and reading your diary. I can’t figure out where your at with this grow. Are they the same plants. If so you’ve changed your lighting DLI, your watering too much or not enough, you need to let it dry out a little between watering, and what kind of nutrients are you feeding. The leaves are yellowing like a N deficiency.

No parecen demasiado sobre regadas, sino puedes levantar las macetas para notar su peso y ver si pesan poco, te recomiendo que con el dedo escarves unos 2 cm o asi sino esta humeda a esa profundidad riega. tambien puedes meter un palo de Pinchitos de madera y ver hasta donde esta mojado. Asi lo hago yo

Stop worrying about amounts and days and water by weight. When the pot is light give it water, when it's heavy don't.

Mabe a Little Bit over Watered but nothing that causes too much worry just let it dry back a lil and try to water more often with less water but 1 l in 5 days Sounds like they Need more water try 300-500ml every day What media do you use ?
