Bro it will be hard to tell you only by the shape of them. I am advising to wait for the smell to know who's who. The terpenes profile of that 2 strains are differents , you will smell more Lemon and pineapple in the Ak and something sweet but less tropical in the Stardawg smell.
Don't let the shape mislead you , the phenotype inside the same strain can lead to differents shape , for an hybrids indica/sativa you can end up with a sativa dom or an indica dom or a perfect hybrid. You can have a bushy plant or a tall one. But the terpenes profile is supposed to be unique, and the Lemon AK is clearly smelling Lemon and Pineaple which is way different from the sugary smell of the Stardawg.
