@kevin r Ok, I replied to you on Patreon. I assume it's just a little damage from LST. I've done it before. Don't look like anything to worry about imo if it's not from pests.
What is the ph you are watering with and are you using cal-mag? Some of the leaves look like the start of ph fluctuations while others look like the start calcium deficiency.

Did you inspect your plant for pests? May be that, or, I've had marking like that on my plant from when I was did LST.
Could you check run off pH and ppm?
yes 6.5 is good
The only time I don't use cal mag is in the first 3wks of veg. Then its full dose of 5ml per gallon every watering.
I grow in coco with dry ammendnents and water with 5.8. to 6.0.
ya cal mag and ph going in is 6.
