I agree, after just two weeks you should be able to determine the start of the bud, but there is so much more growth to go. In soil it can be three weeks until you can even see the base bud structure. That being said, each genetic can be different, though the whites and skunks tend to grow on the larger side, but 2 weeks is not enough to figure yet.

I have a 400watt setup and after 1.75 weeks the Critical Kush is really showing like it will produce a high yield, but my Kosher Kush plants looks like it is still veging in comparison. Blue Rhino has a great start going abd the critical 47 barely has anything. All started from seed on the same day and flipped lights on same day.
