Buckwheat yellowy green. Ok?

I planted some buckwheat as an experiment.
It is coming up, but it is not green like in all the pics I see, but more of a yellowish. There are a few that are green.
Any ideas or recommendations?

I see this post is a month old. How is the buckwheat coming along? I noticed you are on the east coast. I was there a month ago visiting my daughter in Virginia, and it was so rainy, her garden appeared a bright greenish/yellowish. I assumed it was because of all the moisture. Her pumpkins this year are very yellow as well, but it has been like a tropical rain forest there this season. My buckwheat is green, but I have to water the heck out of it to keep it alive in the Central Valley of California. Are you having a wet season this year?
