Ok, so you got them outdoors for the last 2 weeks, but 1 of them you had indoors for 4 weeks. When you were vegging your plant indoors, how many hours of light per day was it getting?? Thats very important because like mogrow said it will probably start to flower then reveg. That usually happens when a plant is indoors under 18 or more hours of light a day then you put them outside and now they are getting 13-15 hours of light. Before I put my outdoor plants outside I always adjust there light cycle to the same as outside. Look to see if your plants have preflowers, if they do then there gonna reveg, if not then you should be good.
