I came back to peek at your journal today and got to thinking about this statement.
When you say mutations in leaves and node spacing, what exactly do you mean? I've noticed a few odd things with mine as well. As the plant grew in heigth, the leaves it was pushing out were 1, 3, 5, 7, 11, 9, and then back to 11 fingered leaves.
Also, about 6 or 7 nodes up, rather then the branch and leaf being right on top of each other, there's about a 1.5 cm gap between the leaf and the branch. It's back to normal for the rest, but it was just odd. I dismissed it and thought of it as a mutation.
Sound familiar?
