Blue himalaya autoflower

I need help. I've gotten conflicting information about indoor photoperiod for my blue him. autos. Much (if not all) of what I've read says 24hrs of light all the way through the grow, from sprout to harvest. Yesterday someone told me 18/6 was his ideal, cutting back to 12/12 for flowering. Which is the path to best yield?

Every plant will be different. That said, I have run autos at 20/4 and one didn’t kick into flower so I put it outdoors

I have 2 in flower right now with 3 more in sprout. I've had them on 24/0 for a while but cut back to 18/6 just yesterday. The sprouts are under fluorescents. The flowering plants are under 280w HPS.... Day 42

I ran 20 on 4 off with autos with great success. Been awhile though.
