Both my Dark Green Zucchini Plants are a slight yellow color. They took on this color after being transplanted into the raised bed. I do not think this is an acclimation problem because they spent quite a bit of time outside as seedlings, and also because they have been the bed for two weeks by now. Also I do not think that it is the squash mosaic virus because that is usually yellow spots that then turn brown and so on. All of the true leaves are fine but the other bottom leaves have started to wilt as you'll see in the pictures. Though that does not worry me as much. One of the zucchinis is not as yellow as the other, but my cucumbers are in the same bed and also have a yellow tint.

Edit: Although I do realize a little bit of yellow is not abnormal I was curious if there was something to help.

Could be any number of things. I do raised beds too and im always working to improve the soil. I'm learning that minerals play a big role. I save up egg shells. Crush them and add to the beds to help prevent blossom end rot. Been adding Epsom salt to help yellowing leaves.

A couple more thoughts: either too much water or not enough, they may need a little shot of fertilizer, it looks like nitrogen deficiency (but don't add too much, maybe some liquid plant food or sprinkle on some 10-10-10). Raised beds, depending on the soil in the beds, may need a little more fertility that a basic fertilizer can supply. Additional nutrients may need to be added every so often.

Egg shells will not do much and does nothing for BER. Epsom salts are magnesium sulphate and have very little effect on squash plants. Unless your soil is extremely acidic it has no effect on most plants. Some swear by it and some swear at it. A soil test will indicate whether you need magnesium or sulphur. Most soil needs neither.
