GDP Auto Outdoor Grow

Both girls are doing great outdoors. Planted the same day as the indoor plants in hydro all getting the same notes & all lived under LED grow lights for the first few weeks. I’m wondering why there’s such a huge difference in development. The indoor hydro girls are quite bushy but seem to be stuck at preflowering. I’ll give them another week or so before trying to change indoor lighting to 12/12 & hopefully nudge them along into flowering.
