Don't rush the transfer. Let them get healthy, from the look of them they could go another three weeks in those.
What are you putting them in? Fox farms was supposed to be shitty, but it always grew good plants for me, with extra worm castings. Subcool method is good too.
Learn how to clone if you can dedicate a small veg room. Worth it. Once you get a mother selected and vegged out, your room setup possibilities get more fun.
Look into screens (SCROG) for those LEDs. Only a few plants, but will be very productive.
EDIT: get a small oscillation fan for the room. And I don't see a carbon filter, plans for one? You won't need much exhaust power with those LEDs. 4" I would imagine, but I used to run HID, so not sure.
EDIT 2:
Go 24hr with your veg. Faster, denser plants.
