They all look good and healthy mate well done! You'll see them explode in 7-10 days! 🌱👍

Nah, she good man. She is a little smaller, but even sister strains from the same mother plant can have different phenotypes. In my experience so far, one will go crazy fast, one will be the runt and the last will be juuuuust right, haha. Example. I have two northern lights growing. Same genetics and mother. One is 5 inches taller but the other is bushier. Both perfectly healthy, just different ☺️ Good luck!👍😉
