Flowers on squash and cuke seedlings

Good thing that it is nearly time to transfer outside because my squash and cukes that were started indoors have started to flower so should get them outside so that they can thrive. I also transplanted my Giant Pumpkin outside inside it was starting to lose leaves and they were turning yellow so I figured move it out now and if it is too early just start another next week seeded directly outdoors. I certainly learned that do not start squash or pumpkins indoors more than a couple of weeks indoors.
