Bruce Banner Auto II

Great answer buy numbers, and I agree I think the smaller light with three larger plants is the reason why its getting to lengthy. If you have the option to move them outside I'd suggest trying that. But look up hardening them off or it could kill em. Sun vs small LED light is big shock for them. Good Luck!

can be genetics.. can be nute-related issue.. could be lack of light for that particular plant or just different light needs than the others due to where the genetics came from in the world - even if interbred, it'll come out 'somewhere' in later generations, randomly. Too much of certain nutes can cause both lanky and tighter growth nodes. if oyu see certain toxicities buld up later in grow, you can look back on this and re-assess if that's a reasonable possibility as the cause as they look healthy to me in the pictures. Light - you have that tiny light covering 3 plants. So, good chance this is why. Stick to 1 or 2 under that light.. probably 1 is best. They only get bigger, lol. ther is no way to tell a male from a female by the way it grows lanky or not.. lots of conjecture out there but it's not accurate in any correlated way. Supposedly taller or this or that.. yet nobody can actually predict it from said traits, so it's simply not true. Preflowers will show up soon enough --that'll be the earlies you can delineate male from female with your eyes. Autoflowers should be all female unless they fucked up and got some male pollen contamination, which would also bring into the equation a chance it's a photoperiod, in some cases, lol.
