The original GSC ( the 1st one ever ) was a plant with a x3 stretch ! Yours is the forum cookies phenotype which is not supposed to be that tall because it was a bag seed found by an ICmag forum users from a bud that was coming from a dispensary ( you can still find the thread on ICmag so you are able to follow the "creation" of that forum cut) so nobody really knows if it is an original GSC or an hybris but these 2 phenotypes have 2 different profile ; and as you can see your stretch is more than x2 but less than x2.5 so it's a normal configuration for that phenotype
