My bell pepper plants look awful.

Ours are horrible as well. They're barely any bigger than when we
planted them, but the peppers are huge, with very thin walls. Because
the plants are so tiny, the peppers lie on the ground and basically
rot on one side.

Strangely, our lettuce is delicious and not bitter at all...and we
didn't use any shading. Weird! It's been 95 degrees every day for a
month, with almost no rain (I water every day).
