seeds pop in different ways,
i had a seed pop and top itself and it took a while to start growing, but eventually it grow 2 main stems.
and another seed pop normally but never grew.
Give it some time to adjust before making a decision.
I’d say you just have a weird mutation of some sort.. within a week or so you should be able to see if it will be viable or if you should start a new one.
Sure you didnt plant 2? Haha
Kinda looks like a shoot with another one wrapped on it, you may have hit the jackpot and have siamese twins.
Give it a week and see how it goes, mutants might surprise you and grow up to be monsters.
