Looks like #2 is going to be the winner. Has an amazing strawberry smell and has great looking and fairly large colas.
#1 has struggled with a bit of cal mag related issues. It's the only one that has needed some supporting. The buds are fairly big and look like they are going to be a week or two early. The hairs are starting to turn pretty quickly, they're about 30 percent now. It still has a bright citrus smell.
#3s bud don't look quite as good as the the other two. They are more leafy and are lacking in crystal. They aren't going to be as dense as the other two. The smell isnt quite as strong but it does smell good.
