Leaf curled

[Lobos]

It's my first grow. Everything was Okey but last 3 days leafs stop grow and curled. Anyone has any idea about my problem.

Looks like a drainage issue followed by overwatering...not positive but the last 2pics look like it might be male also.

Thank you. I used female seeds and I just gave less water now they start to dry leafs.i have 20 pots but only 5 has problems. I really don't know maybe cause of nutrients b 52 and biobizz grow

Looks like the soil could use more perlite... What size pots are they in?

5 gallon pots. I used light mix soil as always. I didn't have any problems indoor but when I tried outdoor something went wrong. I think it's nitrogen toxicity. They got 8 hours sunlight
