They look pretty good to me. Maybe a little small, but it's good for a first grow. One thing I will mention is that your soil looks very dry, may need to increase the amount of water you give. Hard to tell from a picture how wet it is underneath that but it might be slowing your growth if you're underwatering. It looks like your soil already has a little bit of nutrients, but you will probably want to add nutrients eventually. I don't really like autoflowers for beginners, there's not enough room for error and I know I sure made a lot of mistakes on my first few grows. Even if you end up with smaller plants, stick with it because the next time will be better. You can't really beat the experience either of watching it grow and seeing the different cycles, and the harvest. Oh, and since you moved the light back up just watch and make sure it doesn't start stretching again. I have a fan blowing over the top of my canopy, helps with the heat a little bit. Looks good to me so far though, should start flowering soon.
