Strange damage to leaves. Can anyone help?

Hi guys. I've noticed some strange signs of damage to one of the leaves of my plant. There are also a couple holes in a couple of other leaves but it's only to one of the plants. Has anyone else had anything similar? I'm pretty sure I've got my nutes and grow environment quite well set up so could these just be normal? Sorry for the poor quality pic but I've only just spotted them. Thanks in advance for any help.

have you checked your girls and your grow room for pests?

Was just about to say that lol if your sure you didn't do the damage

There's definately no bugs. It's only the one plant too. Who knows. They seem super happy anyway so I'll just keep an eye on it. Thanks for the replys

Did you look under a jewelers loupe, or something? Some bugs are hard to see...until it is too late.

Agreed, some pest come outta of nowhere, it's a lot easier if you treat early and prevent instead of try to get rid of once they're established (which is pretty much impossible)
