Spyder7answered grow question 4 years ago Did you get any nutes or water on them when feeding/watering? I saw some similar holes after either burning the leaves with water spay + LED light magnifying it, and the other time was the first time I attempted LST near the end of week 2, before the plant was ready, and brushed the leaves across the soil. The fertilizer in the soil (that was pre-nutes) created holes like you have, wherever there was soil on the leaves (it was wet soil which made it worse as it "clung" to the leaves).
You have some wrinkled edges too on one leaf which I also had from too much fan (I've since learned to give it breaks from the fan). Other common suspects are fungus/disease or insects: each leaves distinct marks and you need to look at a photo layout showing what the different forms look like. I've been lucky enough not to have issues with either.
I don't think that's a nute deficiency. I did my first grow on almost no nutes, hit just about every deficiency by week 6, and had nothing like that, unless its a potassium deficiency which I didn't run in to, but potassium needs beginning going up pretty fast by week 6. Hope that helps narrow it.
