K high flush on turn, bet too small?

[KKrAAAzy88s]

hand from last week on FTP:

SB posts the small blind of $0.10
BB posts the big blind of $0.25
You have been dealt [Kh Jh]
P folds
B folds
Villian calls $0.25
Hero raises to $1
X folds
C calls $1
Y folds
M folds
Villian calls $0.75

The flop is [4h Qh As] (pot = $4.35)
Villian bets $0.25
Hero raises to $2
C folds
Villian calls $1.75

The turn is [6h] (pot=$8.35)
Villian bets $0.25
Hero raises to $3
Villian calls $2.75

The river is [7h] (pot = $14.35)
Villian bets $0.25
Hero raises to $4
Villian calls $2.75, and is all in
Uncalled bet of $1 returned to Hero
Hero shows a flush, King high
Villian shows a flush, Ace high
Villian wins the pot ($18.40) with a flush, Ace high
(unfortunately I forget what his other hole card was)...

Did I bet (reraise) too little on the Turn?
