I’m growing Autoflower both indoors and outdoors. The one indoor is under 24 hour lighting but it’s also around a week younger than the one outside. They both planted on same soil except outside is planted in plastic pot while indoor is in smart pot. I thought sun is better for Marijuana marijuana plants. Maybe seed wasn’t healthy. Seeds about a year old. First pic is indoor grow and second is outside. Both also same strain Northern lights auto
Looks like you may have leaf miners on the outdoor plant. Possible they could have stunted it. That being said, no two seeds produce the same looking plant.
