This is my first time growing a garden. My zucchini plants were growing fine until I noticed the bigger leaves started to turn a pale color.
That is natural. Since those leaves are so big the plant can not give it a bunch of nutriance, so it may turn more pale. If it is affecting your Zucchini fruit than that is another thing. It is normal.
We have had a lot of rain here; not sure if that is the issue. However, the first 4 zucchinis were fine. Thanks for any help you can give.
This is normal for many varieties of zucchini. There is no cause for concern here. It is just like spots on a dog. Some are spotted, or striped, while some are black. There are many to choose from!

They are planted in raised beds. We have been getting lots of rain here, could it be chlorosis? If so what should I do to stop it?
Yes, this Leaf Spot issue is likely the direct result of wet weather.
Pull back the mulch to help allow air circulation to the plant and it's root system. It also will help the soil dry out.

Plenty of blossoms, small zuchinni growing and then stem end turns yellow.

I have planted cucumber and a variety of squash plants directly in plants with good soil. All of the seeds I planted have sprouted and are starting to grow but the first leaves are extremely small. Is this due to a nutrient deficiency or?
It is likely lack of adequate sunlight.
Increase the amount of light or even use a grow light to help them.

Hi Again, Everyone; I was checking one of our Zucchinni plants this evening because I noticed the leaves are looking really strange. Not only are they turning yellow and brown and getting brittle, but some look very pale, and in the center of the plant is some sort of white stuff that almost looks like frost. Of course, I know it's impossible to be frost because it's June and I'm in the Sonoran Desert. Anyway, upon closer inspection, I think I discovered what the culprit - or should I say culprits - are. I noticed small insects gathered on one of the leaves. When I looked on the underside of another leaf, it was covered - litterally - with what I think were aphids. They were very small, about the size of a pin head, and green. I looked on another leaf and it had the same thing. Then I realized the other insect I was seeing were small ants. I'm afraid I believe I know the answer to this question, but the plant should be removed and destroyed, shouldn't it? Thank you and have a wonderful day.
This sounds like Aphids!
Start to treat them right away, they can devour plants and spread.
I like Neem Oil, its organic and safe for people and the bees.
