Pumpkin/squash plants grow small immature flowers as the plant grows and vines out. The plant decides later when to put energy into the flower to bloom.

Ha! Same here! Here is a picture of my pumpkin on June 7 and it was same size as your plant. I didn't expect any female flowers until July.

I've since picked off that flower and a couple of others since. What variety is your pumpkin? This one is a Dill's Atlantic

weird! if I get females should I pollinate them?

and I don't know what mine are; but the ad claims competition winners

you might be able to help there is a leave that is going Yellow along the central vain on the leave in spots! there was a leave with a small amount of powder mildew but I removed the leaf. after enclosing it in a bag to suppress spreading.

mine have now also put out its first tendrils and leaves have almost doubled in size! so something is going well!

I'll upload image tomorrow! :)

that's mine at moment as you can see there is some yellowing.

Hey Leo... looks like you plant is about same as mine at this point! Took this pic tonight.

I don't think I'd be too concerned about that yellowing. Doesn't seem too severe and like you said it seems to be growing well. I'm not expert enough to know if that's from too much/little fertilizer or water or what.
