My Child Hates Solids!! What's Wrong With Him!?

Alright so here goes, my baby boy is 7 months old (born June 5) and has been EBF until about 6.5 months when we started supplementing with formula. At 6 months we started baby led weaning and tried that route. He hated it. Rarely ever put any of the food in his mouth and when he did he would never do it again. So I waited a little to see if he just needed time.... tried again and same thing. So I switched to puréed foods and that has been hit or miss. He usually spits everything out and gags a lot. Now I am kinda doing a mix of the two but still same results. He isn't eating what he "should" be and it's starting to worry me. Anyone have any advice!? FTM here and in over my head haha. 
Also right now he is currently cutting 4 stinking teeth so his appetite is slim to none. But I plan to try again after they are through. 
Thank you 😘
