So I assume you're in the second or third week of vegetation, make sure to water just enough for it to grow even more! I agree that in 1 week you could start doing LST without any problems.
@Frm1101 the first plant has been like that since day 1 im not sure why but i did over water all 3 recently and am trying to figure out a new watering schedule i havent watered for 2 days already soil is almost dry
Watching the video again, I see that the first plant has claw-shaped leaves. Did you overfeed it too much? Excessive watering? You need to control it so it can grow even more.
Hey, they look good! You still have quite a bit of growth left, is it auto? You could start doing LST from the 3rd or 4th node. I think it's still too small to apply LST.
Cheers, happy growing!
