just because its bag seed does not mean it wont auto flower.you don't know what to expect from it.
its way overnuted. look at the sides of the pot. see the white stuff? its nutrients not absorbed into the soil,or clinging there with no place to go but into the soil.
flush good to remove,and next time mix in a little bit of a lighter mix to start the seed in,such as the soil you have now with pro mix or jiffymix with out nutes added.its better to be a little light on nutes than go overboard.
