I believe we're talking about the same strange results. I have a few of them doing the same thing. The way I'm understanding it is that they are what is called "Ruderalis." I'm just going by what I read in the Cannabis Grow Bible. Take a look at pic. three of my current grow. See the similar results? Pic. two shows a real weird bird. Pic. three is the top of another plant going weird. Did you buy your seeds or get them from some stash you bought? Maybe it's a hybrid that needs more generations of growth before it stablizes into a new strain. That's my understanding of what's going on. I wish I knew for sure...
