First Grow (3 mixed Autoflowers, Indoor 2x2) Wish me luck!

It's been quite the first week in my very first indoor grow. While germination definitely threw me some curveballs, I'm learning as I go. Out of the 4 seeds I started with, 2 have sprouted beautifully. However, one Barney's Farm LSD Auto seems like it might be a dud – it just hasn't shown any signs of life. As for my Gelato Auto, I suspect I might have been a little too rough during planting, because it's lagging behind its sisters in size, and it lost a leaf when I tried to remove the seedpod, which sadly had stuck to it. On a brighter note, my Gorilla Cookies and Super Strawberry Zkittles are looking great so far! My only concern is their height – they seem a bit on the short side. Maybe someone with more experience can chime in and let me know if that's something I should worry about. Ultimately, this is all about gaining experience. So, any tips or tricks you seasoned growers have are most welcome!
