GG4 Photoperiod grow

GG4 - Day 23 Looks like different phenotypes? Is that what it is when one had shorter and tighter node spacing then another? I don't really know the fan leaves look the same so I'm comfortable that these are infact the same strain but they are growing differently. When I transplanted them from their red solo cups I watered with real growers and within 3 days I had roots coming out of the bottom of their new pots. So far I haven't feed anything I just had that initial watering after transplant and keeping humidity at 90+% and so far havent had to water. I'm debating on whether or not I should just flip them to flower in the next week or so or try topping again and flipping a few weeks down. I want them to be able to flower and finisn in the same 4x2x5 tent they are in right now.
