a seed?

i had one plant that i had budding for exactly 8 weeks when i cut it down. it had one seed in it and i was wondering what would have caused that. i havent had any males for over a year now considering i take clones from my mums. any explanation on that? and also i have a g-13 arrmegadon and its been budding about 3 weeks now and the leaves are starting to yellow and burn around the edges. what kind of deff. is that?

that seed could hvve com from a MJ hungry bee LOL or a stray piece of pollon from somewhere near.

Your g13 plant sounds like noot burn post some pix and I can properly diagnose LOL.

well theres the thing im indoor i dont do the outdoor shit much and whenever i used to get males (when i was growing bagseed) i kept a real close eye on the "flowers" and i never let them mature enough to open up and release pollen so thats why its so mind boggeling. like id have them sexing and the day a flower would show i would rip the stupid things. and i wish i could post a pic but i dont have a camera. what type of burn/deff does it sound like to you ? i have 2 blueberry one ppp and two g-13's all in the same pot, yes its large, but then again the plants are small too so...., but the only one showing any sign of a burn or a deff. is that one g-13. if i can find a camera illl post some pics
