[Siamese] Sour Crack

Seen this before - it's like a dicot plant; should grow out fine and normal - think how humans have twins. most of the time the stonger one will take over and the smaller one will die. I would cut the smallest. Good luck with your grow! I'll follow along

Wow. Never seen that before. They may fight for root space unless they share the same root system. I would wait a week or two, if you have the time, before planting another. Just to see how they are doing. I wonder what would happen if you just snipped one of them? I'm sure someone will be able to shed some light on this better than myself. Good luck.
