OK everyone, here's the updated photos of my latest crop

So far everything is looking great. I'm really impressed with the Sweet Tooth and El Nino. They've both exhibited fantastic growth, very short spacing between nodes, and quite a lot of branching. The Big Bang is doing well also, but so far the Sweet Tooth and El Nino are just looking better to me. Of course that could all change as time goes on. Big Bang is supposed to be an excellent producer, so we'll have to measure the final success on the yield.
You'll notice that one grouping of plants is larger than the other. The smaller plants were started one week after the first group. The first grouping was started 24 days ago. The last 6 pictures show close-ups of the three strains. The first shot is the profile, and the second shot is directly overhead. From left to right its Sweet Tooth, Big Bang, and El Nino.
Questions and comments are very welcome, as always
