Front derailleur cage on new road bike will not shift I have recently bought a new road bike. On my first ride out, when shifting the the front derailleur onto the big ring the cage would shift over but the chain would not. I took it home and adjusted the height and angle of the cage and tried to remove slack from the cable, I did not touch the limit screws. However this seems to have made the problem worse as I when I shift the front gears the cage doesn't even shift at all. 

Not sure if this will help but here are some photos : https://imgur.com/a/1oVjDLX

I've tried looking for answers online and the suggestion is not enough tension in the cables. When I shift onto a higher gear there is little to no slack in the cable but when I shift down there is a lot of slack again after tightening it up, is this normal and could it be the cause?
As others have said front derailleurs are a pain to adjust correctly, so taking you bike to a local repair shop will save you headaches. 

However, if you want a shot at getting the front derailleur adjusted properly yourself, stepping through a full adjustment procedure is the way to go.

Park Tool has a great webpage and video that walks you through the entire process.
