can i do 12/12 for purple kush autos

[dean]

i have 4 photos going along with some autos in the same room and was wondering if 12/12 would hurt the autos?
the autos will be around 70 days old by the time i'm ready to flip.
my last grow with this strain took 85 days
thanks

I can't say I have experience doing this but my opinion is it may not hurt th e autos much. I'm assuming they are late in flower and may be near on ready, a week or so of 12/12 won't do any harm.

Depends I mean it.might but the growth might be stunted hard to say depending on how strong your light is. Without added CO2 your plant can only absorb so much light I have ran autos on 12 and have still gotten a decent yield but the light I was using was def overkill for the space but if you only have fifteen more days I say go for it they might just take a couple of extra days to get to the same place they got before
