Hi OMM,
I hadn't given it that much thought until you made this comment...I've been checking the trics on the bottom buds all along, remember my other grows where so big and out of control I couldn't get to the tops to check trics there...I could only look at the ones at the bottom.
It makes perfect sense that they would change at different stages, due to light probably and size maybe. But here's a thought...the wonder woman I'm currently growing, the hairs started turning red on the lower buds days before the tops showed any color change.
Anticipation...I know, I can't wait to switch those PE & OG seedlings. I UBT'd them a couple days ago...I'm pretty sure they are female, but a couple weeks in 12/12 wil tell for certain.
