chain rubbing on front derailleur

I've noticed the chain has started to rub the front derailleur on my bike when in the middle and top chain ring when i'm in 8-9 gear on the rear cassette.

The chain doesnt come off or anything like that and the front derailleur shifts fine between the 3 rings.

I've looked at the park tools repair guide and i dont need to setup from scratch and just wondering if i can tweak the h screw as its the chain side that faces outwards where it is rubbing to move the derailleur out a little ?

Also how tight should a chain be on a 9 speed setup because i think its too loose and i'm thinking of fitting a chain tensioner.

Any advice would be great.

    Nope, H screw is a stop, cage position is set by the cable tension, adjust that unless it's hitting the H stop, in which case back it off.
