Looks like lack of lighting/wrong light schedule and 2 different phenotypes.
Few things to consider with autos
-plant in final pots
-don’t stress them out
-read about dli on here and how to use it
-18/6 or 20/4 light schedule
Do you have air movement in the room and fresh air? Are you pH’ing your water? If so are you using tap, distilled, or R.O? That hygrometer you should get off of the medium, as the sensors are reading the humidity of it and not the air.
Autos are actually harder to grow than photos. For what they are, they look healthy. I think you need to get your light intensity in check.
