I hadn't thought about 100 clones lol.
Guess we will have to wait and see what OP says.
What's Happening to my fan leaves?

Was it your mother plant that the clones came from, or did you at least see it?

Sounds like something funny in the genetics then, where they all from the same mother?
It's possible it's a reaction to the nutes, or environment but its tough to say which. Are you running really high calcium levels?

Yes all from same mother.

Your mother?

No,
We get them from a friend who does clones

Maybe ask them. It's just too weird.

G'day Heatherlu,
If it's a clone from exactly the same mother, i'd have to assume it isn't genetic, but something environmental.
Really does look like munch marks to me.
Did the leaves start out perfectly fine, then turn?
Or were they disfigured from the get go?

I know, it looks like munch marks but i have found zero evidence to bugs or anything. I don't get it. They were fine then started turning when they grew a bit bigger...

Any newer growth doing the same?

Yup! they are

Dunno man, if it ain't bugs, i can't rightly suggest what it is, and i believe you when you say there aren't any.
I still find it unlikely to be the plant itself, if all the other clones are fine.
Sorry, not sure i can really help.

No problem, hope you figure it out.

Did your humidity dip? Might've over fed, plus humidity drop. This just happened to me. Humidity was low, temp was like 82, lights were on full blast. Plants went limp a day longer than anticipated, boom. Carnage.

It looks like manganese deficiency. What do you think OP?

General Information
Cannabis uses manganese (Mn) throughout its life cycle and it must be present in all stages of growth. Manganese is present in all professional-quality fertilizers. When combined with other elements, manganese contributes to plant photosynthesis and in the facilitation and utilization of nitrogen. Manganese and iron are both essential elements for chlorophyll production.
Deficiency
Manganese deficiency is quite prevalent in indoor and hydroponic situations. Younger tissue leaves express symptoms first, becoming yellow between veins, a condition known as interveinal chlorosis, while the veins themselves remain green. When severe deficiency occurs, symptoms rapidly migrate from younger tissue to old, and necrotic spots will appear on the leaves, which will eventually die and drop off. Plants will be stunted and new leaves can be misshapen. Manganese deficiency can also extend the ripening of buds, and severe deficiency can mimic a magnesium deficiency.

“Excess / Toxicity
Excess manganese symptoms may not be very different from deficiency symptoms at first. Manganese toxicity may include iron, magnesium, molybdenum, and zinc deficiency symptoms as antagonistic effects. Necrotic rust and brown spots appear on young leaves before spreading to older foliage. Plants can become stunted or stop growth entirely. Note that manganese excess can result from poor soil aeration, and that conditions may be made worse in low humidity and low pH conditions.
Excess Treatment
Excess amounts of iron are rare but if they occur they must be flushed out using pure, adjusted water. Readjust and replace nutrient solution and keep the pH above 5.8.
