Need help, can’t figure out what formula to go to next

My son is 1 month 1 week old.

1st:

Similac Pro Advanced; constipation, gassy, fussy, not burping only farting

2nd:

Similac Pro Senstive; diarrhea, gassy, fussy, not burping only farting.

3rd:

Similac Total Comfort; constipated, not as gassy or fussy, still only farting no burps

4th;

Similac Alimentum; actually pooping on his own with a pretty normal consistency, less gassy but still on and off cry spells Bc of gas, little burp here or there still farting terrible. But not has a terrible rash all over his face like little red bumps. At first I thought maybe detergent issue from someone else holding him but no one honestly has since he’s been on alimentum and I only use tide free and gentle Bc of my other toddler.

So I have done my research. I debated trying Soy next but I have read that really should be your last choice for different reasons. So I am debating to try these different formulas:

Elecare

Nutramigen

Gerber Soothe - I worry this would be like the Total Comfort and costipate him though but maybe he has a all around issue with Similac...

Also switched bottle tips to a faster flow which helped a little. Debating trying an anti colic...?

I need advice please moms help a girl out I’m desperate... single mom of 2 under 2 here. My first was a walk in the park compared to this time around.
