Whats the best Ppm range with autos?

I've had a couple of dwc grows and have found success with my regular photo period but I have a couple of autos I wanna try I'm just not sure what the proper ppm should be for them. I know autos are sensitive to nutes so I was thinking somewhere around 75 and 100 for veg and 225 for bloom? I use general hydroponics for nutes they work great and I always use filtered water with a ppm of 0.

Stay low and I wouldn't go over 600ppm
