not lookin too hot there. i have the same problem on a few of my leaves, brown spots and some parts where bugs have been muching. did you plant directly into the soil or did you buy some soil?
Remove all the brush around the plant and get some sns 209. Sns company gives out free pest controls just pay for shipping which is $5:65. Hopefully what ever is Messing with your plant another bug will come eat it. Look at the plant very early in the morning.
