Day 48 Autos No Buds Yet!

Hey I have a White Widow and a Northern Lights auto both at 48 days sense planted. I have them on 24 hours light. They have white hairs on them everywhere but they say 8 weeks tell finish for both but not even any bud on them yet and its almost 7 weeks. I see other peoples grows with the same strain and there buds are getting big at day 48.

The one on the left and front are the autos

Maybe try and trigger flowering with a dark period? That’s what I would try. Or just go 12/12

going to try 18/6 because i have some non auto fems in the tent.
