Is this from pests?

Plant has been taking off and besides a few minor issues seems to be pretty healthy. I noticed these holes recently on just a couple leaves. I've checked the leaves top and bottom but can't see any pests by eye. I had a Calcium def issue that I corrected recently by switching to RO water with CalMag...I did a few nights with a foliar spray as well. Just after that is when I noticed this. Could this be from the foliar spray or more likely pests?

I got some Spinosad that I am going to try just in case. Any other advice would be awesome thanks!

I see a few leaf tips missing. Looks like they browned up and broke off.

I don't see a pest issue in the pics. Could be some droplets on the leaves and then burned by the light.

Yeah I had a couple CFL's too close and the leaves raised up and touched em. Burnt a couple tips lol whoops

Thanks, I feel like that might be it. I'm gonna do a round of treatment with the Spinosad just to be safe I think.
