I have a Argon Road Bike
Right now every time i go riding there is all this grease leaking from the bottom bracket.
on chainring side
the bottom part is all tight still and i cant see any cracks
why would grease still be coming through and how do i stop it?

How much is leaking? Looks like it has an FSA external bearing BB. It would have come greased from the factory so probably isn't over packed. There really aren't much in the way of seals to keep grease in on those so there will be some seepage especially when new.

Need to know what you've got. As I said, the specs I saw were for an FSA external bearing BB. Those are not really serviceable so, if that is what you have, they might have just pumped additional grease into the cups which might explain why it is coming out.

As long as you do not detect either grinding or play I personally would recommend that you wipe away the excess and ride on. Better to have some come out than dirt and water go in.

Ok I will ride it out for now, and see what happens later on
its a full built in Sram Crankset
the type that is all connect to the main chainring part

This is no big deal at all. Actually the grease leaking out will wash out dirt that may have other wise entered the bearing. Just wipe it off and be on your way.
