Hmmmm... it's awfully lime green, isn't it. I wouldn't worry about the spots - some plants just have some weird coloring at the very beginning so no worries... And, since they're autos, it's FAR too early to be putting her on nutes (the color suggests they need some nitrogen BUT they don't like nutes until they're about 2-3 weeks old)... I'd just let them do their thing and see how they develop - The only thing I would ask is if you're making certain the PH of the water you give them is between 6.2 and 6.5... other than that, sit back and enjoy the beginning of your grow!
Good luck!
