Unwelcome Critters?

[MidwestGuy]

I just cut these leaves off my girls. I have 4 plants that are ~10 weeks old now and have just flipped them to 12/12 a week ago.

Whatever the problem is is very isolated as these were all I could find among all 4 plants.

Time for some Captain Jack, is something else going on, or not to worry?

The plants are otherwise very healthy.

I think your good. I don’t see any pest damage. Maybe some old nute burn or possibly some magnesium stealing going on there. Plants look great👍

I usually beat up my lower fan leaves. I have a few that look like that.
