Autoflowers not flowering?

If it has shown pistils at day 26 then it is an auto and its flowering just not to your timetable. Autoflowers don't care about light schedule so flipping will not do anything one way or the other, and if she wasn't an auto she would not have preflowered in 18/6 or whatever light regimen you have her under.....

Is the strain supposed to be a 'super auto'? they have been known to take their sweet time as they yield considerably more than regular autos.

Another common question I see is when to switch autos from veg to bloom. Many people are under the impression that as soon as they see the first flowers it's time to switch. Perhaps a little explanation of the life cycle of autos will help to clarify this.

Weeks 1 - 3. Once you've started your seeds and they break the surface of the soil, they are in their seedling stage. The first set of leaves to appear will usually single fingered, followed by a second set that may still be single fingered or perhaps 3 fingered. Once that second set appears growth will start to accelerate as the new leaves provide more photosynthesis. This process will continue, more new leaves, faster growth. Depending on the type of soil in use, mild vegetative nutes can be introduced at week 2. By week 3 most plants will start to show their sex. Males will start to produce pollen sacks and females will display pistols.

Weeks 4 - 6. The plants are now entering a pre flowering stage. During this time the plants should exhibit explosive growth, often as much as a new set of nodes and 1" vertical growth a day. This is the time when they will gain most of their vertical height. Many people make the mistake of switching from vegetative to flowering nutrients at this point, assuming that since they see flowers it must be the proper time. This is incorrect. If the switch to flowering nutes is made at this time the vertical growth will stop and the plant will put it's energy into producing buds. If you need to keep your plants small, or want them to finish earlier, they by all means switch nutes at this point. But if you want to get the most out of your plants continue feeding vegetative nutes until you see the vertical growth slow and stop. Depending on the strain that will usually be sometime during week 5 or 6.

Weeks 7 - 9. By now vertical growth has stopped and the switch to flowering nutrients has been made. The buds will start to fill out and put on weight, becoming hard and tight. Pistols will start to change from white to brown, orange, red, etc. By now the plants will also have developed a strong smell. Toward the end of this phase the large primary and smaller secondary fan leaves will begin to turn yellow. This is an indication that the plant is moving toward the end of it's life.

Weeks 10 - 11. At this time flowering nutes should be discontinued and only plain pHed water fed to flush the remaining nutrients from the soil and improve the taste. Yellowing of the fan leaves will continue as the plant draws the stored energy from them. Eventually they will die and fall off. By the time that the smaller leaves that come from out of the buds will also start to turn yellow. Then it's time to harvest.

I know that many of you are thinking that the seed bank said the plants will finish in 8-9 weeks, so why are you saying they take 10-11? The claims made by the seed banks are somewhat deceptive. If you switch to flowering nutes at week 3 or 4 the plants can finish in the times the seed banks say but they will remain small and not reach their full potential yield. Years of growing by myself and others has shown that autos do best if you follow this time line.

Of course, there will always be variations depending on the strain, the environment, nutrients, etc. This information is meant to only serve as a general guideline.
 
Perhaps you should go down to 18/6.

I tried 24 hour vegging for the first time this grow and the automazar that I had under 24 hours for 3 weeks only started showing pistils last week at day 40; the five other autos I have grown (under 15/9 sunlight) to completion all preflowered at between day 18 and 23.

The other autos I vegged under lights for 3 weeks at 18/6 all showed pistils at between day 23 and 27.

I think plants need some sleep/rest that might be what's bugging her.....
 
Do get a timer though. They are pretty inexpensive. I just picked up another that is digital and has a battery backup so if you lose power it still keeps track of the current time and schedule. $15.
 
Thanks guys! Just ordered a timer today as all I could get around here was mechanical ones. Ill set my alarm and try to get the light cycle started. Just got my therm/hydro meter and im sitting around 70F with 60-70% rh. Checked my water/nute solution that I've been using blind and it showed 6.8 :D the weed gods want this crop to make it lol

Hi I'm having the same problem with my one auto. It's at about day 40 under 28/6 light and it only has pre flowers on her. It's a northern lights big bud from world of seeds. While my other auto is in full bloom for about 8 days now. So if it's not an auto it won't pretty flower under 18/6? Cause I was starting to think it was a regular female seed and not an auto. But it has pre flowers and is still slightly growing upward. What's your advice?
