Nicely done, MGold! Good production there and not much to worry about, as you say.
My 2-cents:
On the jalapeno, after you pluck the first pods when dark green, consider letting some of the next batch mature to full red. I've always picked em green, but since joining the board, seems some of the big leaguers go with the red for a different flavor and heat level. Worth comparing!
Most of my yellowing probs have been related to overwatering. I've got new raised beds this year and it is amazing how much less water I need.
For those peppers still in the beds, consider aerating the soil. When NitWit mentioned earlier he uses chopsticks to do this, I fashioned some heavy gauge tomato cage wire about 10 inches long. The soil in some of my beds were a bit compact, so I poked all around vertically and loosened it up. I imagine this spears the root system and wakes them up. Lots of holes! Allows air and better drainage, nute intake. (I think.) Took about a week and my yellow was gone and growth took off.
I'd say the square foot method worked great there on your maters. Good use of the end of the bed and the fence. You can always whack the vines if they intrude.
Anyway, nice pods, podner....
