Correct ! we have a winner ! :thumbsup: ... alternating nodes indicate when the plant is sufficiently mature to begin flowering, and/or seed production ... this is the point at which I switch my plants to 12/12 lighting schedule ... (they look like that when they originate from a clone, because a clone is, technically, a mature plant, although just a piece of it - IF you've never seen your plant alternate, then you have never vegged a plant to maturity, and you flowered too early) ... :smokin:
