Are they ready for 12/12?

I've had these babies--6 babies in all--for 4 1/2 weeks. They are on 18/6 right now with LST. They seem healthy and are actually a little bigger than they are in the pics (the pics are from a couple of days ago). I don't have unlimited space, only about 24" x 16" x 30" or so to grow in, thus the LST.

Do you guys think they are ready for 12/12 or do I need to wait until the 5 week mark or longer?

Thanks in advance.

hi mate, im no expert but those plants dont look like there doing too great, what lights are they under and are you feeding them any nutes yet?

maybe wait another week before flowering, i waited till mine hit about 10-12" tall before i flowered, which was exactly 4 weeks for me so that gives you an idea, oh and that was under 250w envirolite for 6 plants

You do realize that they are under LST right? (Low Stress Training)

then no, i would wait until they are alot bigger if your doing LST. Depends on the strain of course.

Alright, thank you!
