The last 2 supers that I pulled this year which was about 2 weeks (5 gal) ago was dark like that. I have no idea what they worked to get that. Here in Ga. where I live theres just woods. I thought it might be bitterweed since the pastures are full of them.
In his heart a man plans his course, but the LORD determines his steps. Proverbs 16:9
