Hello I have been growing a sour diesel autoflower, for over 9 weeks, and it has not flowered yet. I read some forums and it says to change the light schedule to 12/12. Is this correct?

If its an autoflower light schedule will mean nothing. Autos do just what they say flower automatically without light adjustment.

If you got a photo instead of an autoflower and were ready then yes changing lights to 12/12 should send it into flower within a couple weeks.
Pictures??

Welcome to the community, the last forum you’ll need for all your cannabis inquiries 
But that information is correct my freind.
Sometimes autos just dont auto and are infact photo periods.
Genetics Sometimes just do not play by the rules 
.
Some people put it in lights out for a full 24-48 hours then go to 12/12, the ideas is it sends a clear signal that its flower time.
But just straight to 12/12 is fine and just treat it as a photo period…

Normally u wouldnt have to switch to a 12/12 u would leave it on a 18/6 but in this case you would change to a 12/12 to get it to start flowering .i just had to do the same with a gorilla glue auto mine was 8weeks old and wasnt flowering

@Deohgie It may also simply be that you have a late bloomer auto. There been tales told in here of some long term auto dilemmas. I hope the forced flip gets her in gear, welcome to the group!!

Switch to 12/12. Grab some clones. If they take will have a nice pheno. My best gg4 ran 9 generations. Came as an auto seed.

@1HappyPappy @Aussie_autos how long does it take for the 12/12 to take affect?

Pistils will appear at the tips of the plant within a week to 10 days. You may just have a stubborn auto. We’ve seen them take up to 12 weeks to flower.

UPDATE: Thanks for all the help, the plant has started growing pistols a week after I changed the light to 12/12.

Grab some clones. Will be worth it i bet. If they die…oh well. You might have a great plant on your hands.
