My auto won’t flower

Change your light cycle..she needs a nudge to flower.

Sometimes autos forget they're autos and need a little help with flowering, try changing the light cycle to 12/12 and after about a week or so you'll notice them starting to flower. Hopefully, I answered your question and remember Happy Growing and Free your mind one puff at a time.

Breeder says 12 weeks in total, so it's not too late. If they haven't started to show sex yet, they probably will very soon.

I saw a good answer to this question on another forum just last night and the answer was this; first off just as humans need a rest period when we work all day we want to rest and when we do its lights out for us as we sleep. your plants need to rest and in the wild outdoors they get that rest when sun goes down. why would you not want to let your plant rest at least a couple to few hrs the same way you do? no matter what you find on internet about running lights 24 hrs your plants do just as much growing in the dark as they do in the light now I cant really sit here and explain the details cause im still learning as well but I do know that there is certain growing reactions that take place during lights on and there are other types of reactions that take place during lights off. So in MHO you should put your timer on 18/6 or 20/4 and see if any changes take place. As long as it is truly an auto it definitely cant hurt to try it out. Hope I made some sense and hope someone chimes in to correct me or agree with me so I can learn more. Happy Growing!

She's a sativa I believe so she should start flowering soon. You seem to be on schedule. Find something to wrap around your little res though, roots do not like light at all.

Consider yourself lucky to have auto's which are vegging longer. Regardless of photosynthesis light deprivation not mattering with auto's, I would still decrease the light duration to give them some rest. Try switching to 18-6 at least, just so they can get some "lights out" rest, this is important. Make sure your nutes are now including higher ratios of phosphorous and potassium, go light on nitrogen. These girls hormones will kick in.

I noticed that some stress or any incident can delay the flowering of automatics. Did you stress her ? She looks big
