I noticed these white spots on the glass they aren’t anywhere else not on the fish, live rock. I do not have snails in the tank either. Anyone know what it could be?

Welcome to REEF2REEF. They could be a number of things. Try to get a closer pic. Wild guess: Medusa stage hydroids

Spirobid worms. Harmless filter feeder. Will scrape off with a credit card if you don't like the look. They're almost unavoidable in the hobby.
 

When to mix up fish meal: When was the last time you tried a different brand of food for your reef?
