damage to the top leaves????

any one got any thoughts, in soil, plant magic feeds (only had 2 feeds so far) 25-30 inch tall, temps 26 on 19-20 off, humidity in 70s, theres 19 in veg just going to switch them but found this tonight, have looked all over theese 2 plants but cant find any other evidence of critters!!! on a couple of other plants there are a couple of slits in leaves but nothing else, ive never had bugs other then spider mites a few years ago, (touch wood) they never come back!!! so am a bit puzzled, any suggestions welcome cheers

Looks like damage from a person, pet, or large bug.

Fan damage maybe?

Possibly a flying bug.

thanks every one, its mad as I look and think moth or something that likes tops of plants but defo cant see one, tried teasing it out with bright light etc, but nothing!! spose ill just be waiting it out and wait for any progression, ill wait till week end before I flip and see
