11 Month old all of sudden not eating solids?

My 11 month old would eat almost everything. This past week though he is refusing most of his solids. He will take a couple bites and then throw the rest on the floor. 🤦 I only offer him what I offer expecting this to only last a couple days but it's been all week. As a FTM, I'm starting to get concerned. He still has about 21-24oz of formula a day, could this be the cause? He just had 4 teeth break through at one time which never stopped him from eating so I don't think it's due to teething.

Any tips or words of wisdom will be greatly appreciated.
