A little sun scald, nothing to worry about it's fairly common with chilies. If you leave them on longer they will turn bright red and become sweeter.

but when i search on google, it says it can cause rot...should i just put them in an area with less sun or something?

I grow a lot of chilies and never had one to rot due to the discolor I see in your image. Chilies like full sun and fall is when I have the best yield.

This is from last fall; if you look close you can see the same discoloration on my Hot Hungarian Wax in the bottom right corner. I usually let them turn red but I had to harvest them before a hard freeze, you can see some of them are orange and starting to changing. Also note the date stamp, it was December.

WOAH! nice job to begin with.. you must have spent a fortune in buying soil and what not. but yeah, thanks for the info..google was just a bit misleading cause typing in "sun scald peppers" you'd think the apocalypse just happened. thanks again.

Maybe scald is a bit harsh; sun exposure would be a better term. Actually it's the time not the cost. Organic gardening does not have to be expensive to yield results. I posted that image and others last fall the link is below.
