m0useanswered grow question 3 years ago Autos are a tricky beast, but they do not go back into veg.
They do not require a light change to go into flower, that is known as a photoperiod.
This is how photoperiod plants got their name as they require the light change, and autos theirs as they automatically flower.
With autos being tricky they will enter their flowering phase right away if they are stressed at all in the slightest.
They also sometimes just do what ever they want as they are special like that. luck of the draw kind of thing as their genetics are all hybrid.
Something to help you avoid this.
Don't over water, over fertilize, use to much light, or transplant them.
All these things will cause them to be stressed and can make them flower early.
Best Of Luck!
