Agreed, I can tell you from the pics (without enlarging them) that you're not going to find amber trichs. They're both still growing
Hairs will turn brown and others will start growing when they do. They actually look ready for the final blowup. I could be wrong, but I'd guess they're about to start packing on bud in the next week
I pick plants early sometimes, it's cool if you want that speedy high, but if you do, keep one and run the other. You'll get the experience of running a plant all the way.
