I think I have stumbled upon what it might be. It is called, "Bud blasting" and I found a photo online of exactly what it looks like. Scroll down this article and you will see a photo that looks very similar to what my buds look like:

Now I have never heard of bud blasting before. Ok. I will admit I am a little worried now. The blog above mentions that the following year she had more doing that. YIKES!!! Anyone know anything about Bud Blasting?
This is about the only article I could find on Bud Blasting:

Sue - I looked closely at the buds and you are right ... each bud is developing 3 tubes as you described. Any idea what causes this?
