$25NL6max: TPNK and flushdraw on turn

[Askilus]

Both villians are loose but I don't have any postflop reads. What should be my standard play on the turn in these situations? On the river I think it's very likley that ha had a 9 so I made a 1/3 PSB valuebet. But I'm mostly interested in opinions about my turn play.

I fold PF. I bet $0.75 on the flop but it doesn't really matter. Turn is fine. Bet $5 on the river.
