Jesu Cristo! 
Okay so then, Carnac the Magnificent, what if I vegged them 1 more week, but kept them in 1 gallons for the rest of their lives?
I have that thread on watching, but I thought I was doing it right!
It said 3 weeks veg, go from 1/2 gal, to 1 gal, to 3 gal to 5 gal!
It also says if the plant is growing fast, leave it in the pot for longer, which I’m definitely doing, but based on the info in the thread, I figured I had another full week before flipping to flower.
Y’all really don’t think I do my research?
I’m literally trying to follow the directions! 
Edit: grumbles as he has to set up the 2x4 to be a flowering tent for a couple weeks
