You will be fine those pumpkins are still small. That first one will be the earliest and could be ripe in late August. I have some small pumpkins (~10lbs) already turning orange!! But I actually like them getting ripe early so I can enter them in the Maryland State Fair. If yours ripen early you could enter them in a fair in your region, that first one has a nice uniform shape. Even if you do get some early it is no big deal because pumpkins store for months and will definitely be ok until after Thanksgiving. I still have pumpkins in my house from last fall.

thank you
