Thanks @InTheShed as we know we had a soil grower try his work on DWC Here and I love the results.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. You're still getting your feet wet here.
In my book, great training is a much better way to control height over flipping too 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).
Myself I’ve been dialed into my nutrients for over two years now , Which always helps . This last grow was 13 weeks in veg and I’m paying for it now , tops are 28” tall (near 7’ total) and over five feet wide on Candy .
CO2 was alright but when you have copd and the CO2 lingers in the room you feel it eventually.
