Yes its possible ;for all those researching for it : i had an auto that last 5 months!!! It reveged after 2.5 months and flowered again massively. With me this happenned when i changed the light setup at 2month mark. The main top bud having epical dominance continued flowering where as all the side branches were vegging and the took extra 3 months after 2 to flower and get ready. It was a northern lughts auto from oaseeds. The trick happenned when i knew nothig about lights and started growing this auto under a mere 35watts of blurple light. After 2 months ;the light was changed to 80 watts of cree cxb3590 and it reveged. So yes it is possible!!!
