Hi, I don't know why my plants are starting to flower it's been vegging for at least 2 to 3 months and I transplanted to my outdoor grow and it's starting to show preflower. Me and my nephew are growing the same strain that he grew once indoor and his is showing flowering more than mine. I took the plants out to get use to the sun and I bring it back in cuz of the light cycle since may and it's been transplanted outside like 2 weeks ago I think June 3rd.
