Back in my soil grows I use to play with the option of taking them outside, back and forth. I live in Washington, where a summer day can be 80-90 and the very next day, low 60s. But as long as the handling is gentle, the plants love the sun, and it's like they open up their arms and embrace it. But also, flowering does take a while, and in your pictures I dont see any white pistils. IMO there's nothing to worry about, your plants look great and they look like they are about to go into full swing. I will say though, any kind of added shock during flower stage, IE moving them, will have greater effects then if in Veg. I personally have noticed this with my own experiments..
