New grow starts tomorow!!!!

After succesfully completing my first grow (top 44) with few problems but overcrowding...
https://www.rollitup.org/grow-journals/171950-top-44-update-pics.html
I am moving on to bigger and better things. Tomorow i am planting;
- world of seeds afghan kush ( fem)
- Buddha white dwarf (fem)
And (possibly)
- g13 Blue demon (fem)

I would like to know if my auto (white dwarf) can be germed with the others and then have its photoperiod turned to 12/12 with the others with no bad effects? i know it may slow it a bit but will it damage it in any other way?

Thanks guys.

so no-one is gunna answer my question?
