I can only follow which plants are which if you write what they are just above each pic, but that's just me!
If the breeder and everyone else here thinks you should flip them at under 12" tall then I'm just a lone wolf (+ Nick) howling at the moon. This is your first grow inside, new nutes at varying strengths, plants off to uneven starts, recently upcanned and just starting to look better.
In my book, great training is a much better way to control height over flipping to soon.
Hydro is much faster growth than soil (check out every single god damned plant grown by
@West Hippie!), and CO2 is a completely different ball game (check out Mr Nick above).
