Does this autoflower look like it needs a 12/12 light cycle to properly flip to flower ?

All the plants in the two photos are in flower..

No, it is either genetically defective or some kind of half-breed issue or it needed more light -- since other plants around it are fine, i'd go with a fucked up auto genome. It's clearly in flower, and hours of darkness given is irrelevant for an autoflower. hours of operation should provide the proper amount of DLI. Whether it is 12 hours or 18hour operation doesn't matter one bit. Hours of operation is just another tool to use to dial in how much light you provide per day realtive to ambient co2 levels or supplemented co2 levels. ~35 DLI for ambient co2 is about all you can give. some trial and error to tweak it based on how the plant grows from there. Some percentage of autoflowers seem to do this. Google image search 'dr grinspoon' - it's a weird phenotype that grew small clusters or individual calyxes over an elongated stem -- probably some genetic mutation that doesn't stop stem elongation sometime after flower phase starts or takes too long to stop it, etc. So you get calyxes sproud out a bit instead of well-formed buds. I've seen this in an autoflower. I've seen it in a photoperiod, too. Seems more common in autoflowers though. The trait definitely exists 'out there.'

Lol cool, 😆 her name is Jackie and she is a beanstalk.

Good advice below. 24/0 is not great, I also think this might just be the genetics of the plant and it might not get better given the other plants around it seem fine. long, stretchy, foxtaily.

NEVER grow at 24/0...........18/6 is perfect. Without a dark cycle, the plant will never function properly.

Seems like non-photo gene (ruderalis) just got thru in flowering. Vegitation still normal (bro-science). Maybe next time start topping. Will try this on some sativa (late-tall) auto seeds I bought. Not really a proof of good genetics...

It's in flower and that's not being caused by 24 hour light, it's genetics. In our auto runs at work we'll typically get about a dozen plants like this outta 4k plants. Just crappy luck in the draw from the genetics pool. It may or may not frost up enough to consider for hash but the flowers aren't gonna bulk- at least no time soon.

Just heavy sativa dominant. They flower longer. 24/0 is too much, i would not recomend, 18/6 works way better.

Iv had a couple of autos that did that and needed 12/12 to flower properly.

Man 18 hours a day of light is more than enough. Give your plants and electricity bill a break for 6 hours eh. 24 hours indefinitely has been stressing them out. 12/12 is always the best solution to get them to start flowering. My critical cheese was supposed to be an auto but it perpetually veged at 18/6. Flipped to 12/12 and she started flowering. So it was maybe a photo period plant improperly packaged in an autoflower packet. I don’t know as I kept it at 12/12 until the end of the grow. However that tall plant could just be down to genetics and how she is programmed to grow. I think you need to definitely re evaluate your practices and make some adjustments to that light schedule. There’s no reason to keep lights on 24 hours a day.

Hey there how's it going 1st off yournoff to a great start your plants look great. I suggest increasing the light amount soon till you get to around 1000. Also it's possible the one plant taller than the rest you can bend it over and let more of the plant get better light. I would not worry about the size of the buds yes they will get larger. Light is a very very important factor in density and size. Your at the point in the grow the plantsbcan take more light than 800umols Good luck don't stress out
