is this common.....one of my white widows sprouted 2 plants in one pot just side by side....and i know i used only one seed the 2nd one popped up about 2 weeks after the first one popped up i have yet to see if they are from the same root system

anyone ever seen twins like this or is it a common thing im a noob ..........

ill check the roots in a couple of days to make sure its not joined as one plant i just want it to get a little stronger first the little one just popped up today and dont want to kill it
