I've come across two weeds that i am not quite sure what they are, at first i thought the one with spines was spiny amaranth. However, the leaves are not quite right and the spines aren't in the right spots for it to be spiny amaranth. The second one, some of them had leaves with red on them, some didn't. I am located in Kentucky. Any help on what these weeds could possibly be would be greatly appreciated!
