Ciujbauanswered grow question 3 years ago Give her time mate , It's just on 3rd week , genetics are different on every seed
I've seen that this strain is Sativa dominant so will do stretch during flowering for sure .
Also if lights are close to plants , that could be the cause , but mainly I do think it's just genetics and no reason to panic .
If you have other plants in same tent(under same light ) and has no light burn issues - it's just genetics
I'm having different plants (photoperiods) on every seed - even tho they are same strain and same seed bank
If that's the only one - have a look at your light manufacturer and see how they recommend the hanging distance .
