bud on seedling

sooo..i had this seedling in a 6 0z solo cup but no where to put it...it sat next to my girl, who is now in 4th week flowering so i decided to transplant this tiny pathetic plant...bout 4-5 leaves all VERY tiny and half witherd...well after i put it in a bigger pot it started to grow a bud on top but has no flowers..is like 6 inches high---anyone know what this is about??

that can happen sometime once i took 8 clones all the same planted them all in the pots and one grew like a lolly pop i mean not a single branch just a big as bud at the top was the wierdest thing ever
