Outdoor Any idea what’s causing this?

First grow. Outdoors. Not sure what could be causing this. Not seeing it on my other two plants. Seeing this mostly on some lower and middle leaves.

Before chasing deficiencies etc, what is different about this one? Slightly different location? Different wind exposure? Sun?

I've chased things outdoor that turned out to be wind damage on one plant getting more direct exposure than the others.

And how low are your leaves hanging?I try and keep things well clear of the ground, more issues with critters with low hanging stuff.

The leaves are off the ground. All my plants are on my covered porch so they don’t get rained on. I move them throughout the day to get maximum sun exposure. The other two are a different strain and that is the only thing that I can think of that’s different between them.

My first thought, if I walked out back and saw this, would be to look for pests. Bugs can see strong and weak plants, and if shes a weaker girl, she is the dinner bell.

Doesn't really look like it...but it doesn't really look like a nute issue to me either.
