Notice that one plant is very different in colour than the other 2 plants, purple stem and and buds. In fact, none are the same colour as the others. Of the 2 green plants one is much lighter than the other.
The 3 plants have been outside for a week. They are growing but are spindly, as in, big distance between leaf junctions. I wonder if I should have topped the plants, but I have read one should not top auto-flowers.
The result you are seeing is from I am guessing it was a widow grow inside. Lack of proper light caused that. Now outside since it has only been a week you won't see a lot of difference yet. Plant is getting acclimated to soil and sun. They should start growing about now. Plants outside tend to be more stretched, and spread out compared to indoor grows. Not sure what will occur in your case.
