nah, the most i have is 9... and im 3 months in, 1 to go... never seen a 13 blade leaf but im sure its possible, especially with a pure indica
Ya dude the same thing is happening to one of my plants. Your leaves are actually almost identical to mine in everyway except mines a little bit more indica. Some of my sets actually have up to 15 leaves now! I tried to get an answer as to why this is happening but no one responded....anybody have an idea?
