Low water pressure in shower after repairing 1/2" PEX

[Ed Reinstein]

I put in a niche in our shower, accidentally nicked the PEX tubing. So I bought the fittings and the sharkbite clamps and fixed it. It doesn't leak but the pressure is significantly lower . I'm stumped and can't figure out what I did, any trouble shooting ideas?
