yeah, its important to grow your plants in vegetative untill they have a proper amount of preflowers even if they are clones or feminized. it also depends on the strain. do you have bud formation? you should definately be seeing something after 17 days or your plant is facing some sort of shock. make shure your room is light proof as much as posible and that you are not turning your lights on during the dark periods; this will mess with the plants proccess of producing flowers. they look healthy though!:jointsmile:
