I'm the same way, my friend gave me a free $20 sack that he got from his friend. Tempted to smoke it, but, I might just wait till I harvest so I can compare the two back to back.
My side colas are having more orange hairs everyday as well, and swelling fast. The top colas are twice the size of the side colas, yet still all white hairs. It's weird.
The top colas have pistils like albert einstiens hair.
Oh and all Cloudy/Amber at the moment, very little amber on side colas, a lot on top colas.
So if I'm lucky I'll have top colas for days I need for my pain, and side colas for my working high.
