What is the longest time it took for an auto to flower for you?

New here and this is my first post! I am a newbie to growing but do have few grows under my belt now over the past few years, some photos and autos alike. I've always grown organically in soil but this is my first time growing in coco and in Autopots using the Canna nutrients line.

I must say that I was absolutely floored by the explosive growth I have gotten with this Autoflower run so far compared to previous soil grows. One literally reached 6ft tall before flowering! I've had in the past, 6 autos in soil/3gal pots that did not fill my 3x5 grow space like the 3 I have going now....2 Strawberry Gorillas and one Gorilla Cookies. That being said, I'm getting concerned with the Gorilla Cookies auto as the other two SG have been flowering already. One started to flower on week 4, one on week 5, and this Saturday will start week 7 and the GC has not started flowering yet. It continues to grow and bush out and it looks like it is ready to start flowering at any second second but it hasn't yet.

From my personal experience, every auto Ive grown flowered between weeks 3-5. So my question like my title asks, what was the longest it took an auto to flower for you? I've grown this same strain from the same bag of beans I purchased that didn't take this long. Is this normal?

I was doing 20/4 on the lights then last week bumped it down to 18/6 to see if it triggered anything. I know it's an auto so it shouldn't matter but thought it might be worth a try.

Any ideas? Thanks in advance

The gorilla cookies in the picture is the one on the left. The lighting seems to make it look yellowish but it is greener than it appears.

Sometimes the auto gene dose not take and and you will have to switch to 12/12, it should still flower faster then a photo equivalent

The amount of threads here with autos not being auto agrees with you.

I was thinking of going to 12/12 next. I just hope that the flowers will have enough time to put on some weight before it finishes. Thanks!

The ruderrails strains produce such low quailty flower, and the autoflower trait is so unique amounst canibus it takes a lot selrctive breading to get to the fire buds we pull down 70days from sprout now

They will, they will not finish with the others, how ever long the others have been in bloom until you switch to 12/12 is how long it should take for them to finish, maybe a week or 2 longer then that bc they dont have a strong a take of the auto gene

sometimes.. but still is erratic at best. I wouldnt call it guaranteed fire any more than regs

True but I think alot of that is down to seed mix ups down to photos being accidentally sent Vs autos as well as some just not being day neutral

Update...I decided to remove the two strawberry gorillas and set up them up elsewhere giving the Gorilla Cookies the entire closet space as I can seal it tight with no light leaks and put it on 12/12. This was done the day I started this post on 2/20. It does appear that the budding sites are starting to develop more now and it really filled out the whole grow space with the extra room it has. I think it grew another foot and is over 6ft tall now!

Kinda weird that the 3 other GC seeds from the same bag, that I grew in previous runs were a fraction of the size and all flowered by week 4. They were grown in cloth pots/soil though, not in coco coir/autopots.
