Buckling hardwood planks

nytimes770 said:

I've got two hardwood planks that gradually lifted up on their long edges over time. They're not lifted up that high - i can hardly tell visually. The house is 5 yrs old. Google tells me it's most likely due to moisture but i don't know if that's the case.

What's the best way to fix this? Should I nail it in or use some sort of wood glue or epoxy? Or even this product: www.fixafloorworldwide.com
