Yellowing zucchini leaves

Update on my previous post....the yellowing zucchini leaves are not getting any better. The new leaves are yellowing as well :(

Both of these are my yellowfin zucchinis that I started from seeds. The odd thing is my gem squash plant right next to it in the same raised bed doesn't have the same issue. Both zucchini plants have multiple male flowers and 2 female flowers so far. Gem squash only has male flowers as far as I can see.

Is this a nitrogen deficiency? But if it is, then I would expect my gem squash be in the same trouble as well? Hoping someone can help...thank you!
