Except for the peas, which would benefit from an overnight soaking, all of the rest can be direct sowed into the garden without concern. As long as they are planted correctly and the soil and air temps appropriate, they will germinate fine without any intervention. And no reason to add any fertilizer. The seed contains all the nutrients necessary for germination and early growth. One is not recommended to fertilize planted seeds or germinated starts until they have at least one to two sets of true leaves.

I can’t imagine attempting to sow wet lettuce seed. It’s hard enough when they’re dry and not sticking together and to one’s fingers.

I don't pre-soak my zinnia seed.

I knew it sounded kind of suspicious. Thanks for your feedback!

daleyc, the only benefit to soaking those seeds large enough to conveniently soak then handle - is soaking can allow moisture not nutrients to penetrate to seed coat and begin the germination process. But again, in those seeds that are large enough to handle which have less penetrable seed coats ;0) No need for any fertilizer before any seedling has true leaves - it's already there and present.

Within the seed coat is the embryo and nutritional materials used
to sustain the germinated seedling until it is able to make its own food
via photosynthesis. You might start with a very diluted fertilizer after a set of true leaves have appeared, nothing to gain by rushing it - or doing it before germination takes place.
