Height of the closet will be important. Most folks go to a foot, foot and half indoors before flowering. If you're growing sativa, make that 6 inches to a foot. You may employ LST or other techniques that effect this.

With a 1K watter, you'll have to leave some room between the light and tops to avoid frying the plant.

How long it takes your plants to get to the end of vege depends on many, many factors. A big ballpark to figure on would be around a month from germ.

Your babies may be a bit cramped in that setup, and you may have heat issues with 1400 watts cranking in there. You'll likely need active intake and certainly active exhaust.
