flowering with hps 24/0?

If i am correct in assuming that you cannot properly flower with hps 24 hours a day then how would you do this situation

4 autoflowers.
3 Fem

Been running 600w MH for 20/4 and its time to switch over to HPS for the fems. Is there anyway to safely do this so that the autoflowers will still flourish and for the fems to kick over to flower

auto flowers....wait for it.....flower automatically no matter how many hours of light they get. probably better to give them more light but then your photos won't flower. You could just keep trucking and veg those feminized seeds and let those autos do their thang.

just busting your balls little, sorry if that came across as douchey. Glad I wasn't recorded on an international forum when I was a newbie. Funny thing about farmers is their always talking about the next grow or year, because the learning doesn't stop.

just gonna have to run the autos under the 12/12 cycle with your fems. they'll still do fine under 12 hours dont worry.
