Purple stems and strange leaves

What's up everyone this year I'm growing some skunk #1 outdoors and 2 of the plants have dark purple stems and one also has smooth leaves that are curling downward somewhat. The buds seem fine so it may not be a problem but figured I'd see what everyone thought.

Appreciate any help. Here's a few pics of some of the other plants, getting ready to chop a few down soon.

Just wanted to say your plants look great.

Thanks man appreciate it, like I said may be nothing I need to worry about but it's definitely different.
