What's wrong with my bud sites?

[Peppersmr]

I've got 2 plants growing, this one in particular (the other is fine) is having an issue I can't identify. The pictures you see are now the second bud site this is appearing at. The first one I snipped off and it seems to be ok as does the rest of plant. Any idea what this is?

I don't see anything that would cause me to panic. Any other information that you're concerned about that you may have left out? Looks healthy to me. Maybe a pH swing after you watered last, but that's about all I can see.

I'm sorry I wasn't very specific about what I was concerned with, those two spots on the leaves that you can see in the pictures are my concern. They're very dark in color and that particular site just looks wilted, but as I said the rest of the plant looks healthy so I'm not sure...

It just looks like the pH temporarily swang. From what I've read here and again is that is what happens when there's pH swing. I hadn't heard the actual science behind it though. But it's a fairly common issue. It's not going to wreck your plants too much. They found a problem, and that was the best way the plant could fix it without completly killing it's self. My feeling about it anyway.

Looks like you spilled nute water on them. Not much info so Idk if you had a light get too close either.
