Last year I had 2 pots of pepper plants, green peppers, and this year I've noticed the leafs have yellow spots on them. It doesn't seem like this is effecting the peppers themselves, it's still producing but I was wondering what could cause this. I've read it can be from the chlorine or not enough nitrogen, but i fertilize it weekly.

here's 2 pictures of the leafs:

I also have tomato plants in half of a 4x4 ft raised bed. I know they're really close together (I guess I didn't expect them to take off so well)

But my question is this: many of the flowers have fallen off leaving it absinised(?) I've read that this can be caused by the temperature being too high for certain types, though it hasn't been much over 80 yet (even t hough this is texas). I also read it could be from over fertilizing or over watering though i've stopped fertilizing and I try not to water but once every 2 or 3 days. Any other suggestions?

And one more thing: I also have zuchinni in my garden and a few of the plants have really taken off, and one already has 2 zuchinni on it. about the middle row, however, has started to die, I thought this as from overcrowing but was just wondering if anyone had any opinions, the leaves turn brown and curl at the ends.
