Them are some healthy looking girls you got there. What strains are those? I got a GSC right now that has a similar symmetrical long stemmed fan leaf sets. Just wondering if we may be related. 
Welcome to our happy hippy home @hippieman. 
It was Gorilla Glue bro
Look good:heart_eyes:
That doesn’t look so much like GG4…
It’s usually very stretchy with lime green flowers/buds, and dark leaves, foxtails, prone to purple petioles.
They stack more like a sativa… here’s some Medgrower1 “bringin’ in the glue”…
And some of mine; same cut as Med’s…
Your plants look great, but they don’t look like the glue I’ve seen before from Medgrower1, Mr.Tight, (both from Michigan), and the clones I got in Michigan.
Is it possible that they’re something else?
Yes possible. They def have the glue smell to them and when you trim and bag the trim very burnt tire as well.
I’ve never heard of a burnt tire smell from GG4…
More of a strong “pine” smell.
The first time I tested an immature bud it was like smoking a pine cone…
that looks like GG#4 right there 
Yes it was man I want more of that sorry for the wait lost internet for a bit
You have beautiful girls man
