Okay. You are going to need to know the breeder. Then check what genes each strain holds.
Indica will have fat fan leafs.
Saliva will tend to lean more on the long finger typed leafs and tend to have more fingers per leaf.
So to me l, just guessing now. The 1st is leaning more on the saliva side. The 2nd will be the skunk as I reckon that's a full indica?
Have a look at the strains and you'll be best to figure it out like that and check out other grows of the same breeder and check out how their leafs look. But either way it'll be hard unless both strains are close.
Good luck.
