Hard to tell because it's in such bad shape but if I had to guess I'd say Indica. Even though the leaves are thin they LOOK like they should be fat and look more like Indica leaves than Sativa leaves.
Hard to determine since there are so many strains and hybrids nowadays. Plus your foliage is sort of suffering but it does appear to be indica dominant. narrows the search for the strain but there is still alot to siff through.
Its impossible to determine what strain it is unless we to DNA tests. Anyway, I agree with the others. It is Indica dominant and its stressed. It looks like it was re-vegged.
