Where is the 2nd true node? That part confuses me.
A node is where your leaf pairs come out of the main stalk. As the plant matures, this changes from pairs on alternating sides, to a single leaf on alternating sides. For the sake of topping - you'll want to go from the bottom, skip the first node (the one with your original, single blade leaf that came out first - not a "true" node), count up two, and cut about an inch above that.
Ok I see what you mean now. Cant you see all the tops now though?
If you mean in your pic, no - the second plant it looks like you were successful, I can't tell how many tops but you did change it. (Looks like four from the pic) The other, that you were wondering why the leaves look funny? I can't see any new tops. The leaves look weird because it's where you cut them. In a successful FIM, they don't do that. I thought the same thing first time I tried FIM - but I just managed to stunt her growth, and got nothing to show for it. A successful FIM (or topping) creates new top colas, but there are always still more side branching that resemble colas - (while in vegetation, anyway) maybe those are what you're looking at. Here is another example - same one of mine as above, just 24 hrs. after I topped it, and the same plant one week later. You can clearly see that there are four tops on it already.
