hey there chacazulu, that's good luck right? happened to one of mine aswell in one of the diaries under LEDs, anyway what you want to do is carefully seperate them and grow them individually, in my case i got one runt that randomly died overnight several weeks later and one normal that gave a decent yield. sometimes you get two runts sometimes you get two normal plants, but you do need to seperate them otherwise their root systems will start canabalising eachother and stunt growth on both. Hope this helps ! 🚀
