Why are the leafs looking like this?

Drastic training degrades size of leaf. A reraly see 9 finger ones on defoliated once plant, have sometimes 13-14 fingers on untouched girls ...

I grew that exact strain before and my leaves were not that narrow. You can check it out on my diaries. Newer leaves will be smaller and more narrow but will obviously grow more in size the bigger they get. But, Your seed probably carried the predominate sativa genes so you will likely have thinner leafs and also a taller growing plant. I enjoyed growing that strain and it turned out very well. Just know it does grow very leafy so you will be trimming a lot. Hope this helps.
