Nice update bruddah!! These look great... especially the JTR. I love that plant despite never growing it... it just looks so... so... SATIVA! I bet she's a winner despite any pollination that may have happened.
As for the LED alien glow, lol. I think part of what you're not liking is the color temp in those shots? The blueness? If that happens to be the case, you can adjust it "in camera" by setting your color balance setting to Flash, OR when you're on your computer downloading the shots and using whatever program you use to process your images, you can normally add some yellow color wise. Sometimes you can do an auto correct, and then warm that up a little bit more, as auto correct is normally just a good starting point (and sometimes it just fuks things up more than anything else-- depending.)
If, however, you are looking for something a bit more organic feeling, I'd say you can never go wrong with natural light... just throw your plant near an open window, and put something black a foot or two behind it (big poster board works well) that is not in the window light as much so it really blackens up. Assuming that your window is to camera left, then throw a big piece of white poster board to camera right in order to help bounce some light back in, and open up your shadows so that they are not as harsh. But honestly, that ring flash kicks ass, dude. Just warm it up some-- and send that alien packing!
