my 1st grow

[DanKnuG]

right now i got 5 plants, 2 just under 2 months old and 3 just under a month old. there all mystery seeds and think i may have a problem with one plant i got from a friend. it was transplanted like 4 times due to his father noticed it... witnessed relocation lol. long story short is that he gave it to me and there this brown spot in the center. its also been bitten by random critters. i am wondering if i should be worried about this.



this is the plant i am concerned about, ill post pics of the others in a little bit
