The entire plant is looking fantastic, just this 1 branch, the lowest or first 1 to form has never grown like it supposed to. The other 1 is allready gone for 1 month. Ive pulled it of because I dont like the colour of those leafs.
It might just be a genetic mutation? The rest of your plant looks great and I don’t think it’s a lockout or burn. Especially since it’s just on that branch. There’s a guy named cannabis_potency_reasearch that grows mutants.
