I got some pressure treated recently at Lowes and some of it has a green
powder substance on it. It sure looks like mold to me. It doesn't look
like it's from the pressure treating, and it just so happens my
allergies spiked when working with it. Anyone see similar and know what
it is?

BTW, I let all the PT wood dry out and any that warps I return to Lowes
no problem.
