I really like your way of growing autos! ✌️
At start of the 3rd week, day 15 - theres a pic of the seedling wrapped in a small root space. Are you just doing it to get a solid rootball before the seedling starts to spread all the roots all around the bigger air pot?
Or are you intentionally restricting root space for the first three weeks to get the autoflowers to flower faster? As autoflowers internal clock is based some way to the tap root/root mass. I think they’d tend to start flowering faster in a small root space and it also helps to keep them moderate sized.
As they start to develop pistils or just jump into the bud set-phase you could take the wrap off and let the roots spread, so you get a small plant but HUGE flowers!
This gave me a lots of new ideas to test with the autos in case growing them as "a normally potted plants"! 😎🙏
