Definitely check for pests because it looks like that but if you can’t find any and no sign after using some sticky traps then use a dose of cal/mag with your next feed and assure you Ph is on point for your grow methods.

looks more like bugs/pests biting it.
leaf looks heathy ... inspect underside... maybe use a scope to see the tinier pests.
if you watched it progress and are certain it is something else... lower twisted leaves would help confirm a Ca-def.
i'd look over your dry amendment labels... it likley contains Ca. your soil likely contains lime of 1 or 2 sorts... Ca is in your water, unles using RO etc... Usually ca symptoms are ph or lockout related when i see them on here than an actual Ca deficiency.
I'm still putting money on a bug/spider or a passing bug that took a taste and moved on..
