After much trouble trying to get those seeds to grow, it was an overall failure with 4/5 seeds failing to germinate fully. For whatever reason, they just wouldn't surface. Only Diaz (above), after a bit of trouble, has been successful. So the new plan is to try starting another autoflowering seed and grow 3 plants total, only one of which (Diaz) will be a photoperiod plant. This will allow me to set the lighting schedule largely based on Diaz's needs without having to worry about alignment with other plants.
Diaz is tiny still, Santiago is getting big now, and both seedlings seem to be healthy.
