hard to say for sure but it does look like it. 5 bladed leaves that have a red strip on them is who i can "usually" tell other way is the smell. every one grows different but the smell is same. looks real nice.
I grew this cut a few times. Its dependable and a large yielder. I don't have it around any more but my friend ended up using a Purple Indica x Bubbleberry/Yumboldt male on it... so that should be a fun cross.
