I accidentally misted my seeds with a vinegar/water solution instead of my water only bottle....my veggie seeds have just started to grow just the tiniest bit...are they doomed?

Vinegar can be an herbicide, depending on its strength. Your seeds may not survive this but if they do, you'll know within a day or two.

I'd mist them w water first thing in the morn, if you let sun get on them they may burn?

No, the water evaporates too fast.

no, no, I meant the vinegar may burn the plants if it still has a residue on the leaves, so mist them off so that the vinegar is not on them before putting them out in sun or under light (?)
I'm thinking vinegar + strong sun may = sunburn?

Wouldnt the vinegar evaporate, it is mostly liquid?

I guess, don't know if it leaves a residue or not?

Not enough to hurt the plants.
