I'm not sure that's true of all nutes, but it is definitely true of cal-mag. A number of growers here (Penny included) stopped using RO water because of all the good things it was taking out.
Always good to start low, but I'd bump it up with each feeding as this is an auto and the clock is ticking toward pistils.
Thank Shed
