Ok so im week 3 into veg, i just noticed these tiny spots on the ends of a few outer satellites im keeping an eye on it but id love more opinions on what the possible cause could be ,. Bellow is a list of whats on the menu and light info etc., My personal thought is that because i foliar spray every 4 days about 3 hrs before lights on, maybe i made a light adjustment prior that caused the spotting from light burn? idk any help is greatly appreciated.

They live.! And are probing your plants 
Maybe check the underside of the leafs, and let’s hope it’s light burn and not some critter

Welcome to the community. 
What’s the purpose of the spray?
And what kind of spray are you using?
Have you had bug problems in the past?
If spray is necessary, I would spray just before lights out. Water on the leaves, can or will burn spots on the leafs, if not dried before the lights come on.
Like @BetrayedSoul said, do you have an overall picture of the plant?
Good luck!

never had any bug problems i live about 500ft from ground level in the heart of the nevada desert, in the last year i saw 1 fruit fly when a banana fell behind the bread box, but it looked like it was sick and having trouble flying

Overall your plants look good. I think if it were me, I would lay off the spray and see if they get better.

Ok well quick update, i am almost 90% sure it was due to using foliar spray too close to lights on, i no longer see the issue and it cleared up after i took a break from foliar spraying. thank you all!
