Hey Buddy, good to hear from you. A plant can be flowered when it has alternating nodes, that is when the leaves begin to alternate, or not 2 evenly spaced across from each other on stem.

You need more light. If weather ok, leave outside in sun as much as possible. Can flower under 400 watt High Pressure Sodium bulb (HPS) at any time. Flower at 12 on and 12 hours light off.

Hope this is helpful, my South American friend.
