.50/1 - 2nd Set + flush draw vs pot on turn

[redCashion]

I think I should have lead out on the flop, but what is my action on the turn? I have a solid hand, a nut draw, and a possible low, but for some reason I didn't feel comfortable with where I was in the hand, probably because I didn't bet the flop. Thoughts?
