Question about the G-13 strain

I was curious as to how I can tell if my G-13 plant that I have growing is pure indica, or if its a hybrid strain. If needed I will post pictures of my leaves.

fat leaves are indica and thin leaves are sativa

if you post a picture we can give you the ratio of indica to sativa, like 80/20, meaning its not completely indica
but if the leaves are realllll fat and short its deffo indica

here =are about 4 pictures. hope this helps.

that's definitely not pure indica.

id say 50-50 or 60-40

nice so its not a pure g-13. any suggestions on what g-13 is commonly crossed with?

I see the most common cross breeds with the plant are hashplant, og, and haze
