@texaskitty111, looks like squash bug eggs:

@AR, kind of looks like something funky happened in that one spot in that planter, going mostly by the last pic. Maybe someone dumped a beverage? Dog pee? Could be powdery mildew. If the sun isn't shining on that planter for at least 6 hours, it may not be enough for these full sun-sters. If you think that might be the case, watering only if really dry could help these plants for what's left of summer this year. Next year, you might have better luck with less-than-full-sun plants, those in between full sun and full shade, if you determine there's not 6+ hrs of sun hitting this planter.
