I can comment on dosage if that will help, organics you can get away with using a higher ec although i never personally advise this as its only because the plants tolerating it probably due to any organic compounds present that happen to give a reading.
600ppm (1.2ec) hanna is about the max of an auto however i did push a very big girl once, to 630ppm before i saw issues.(i use synthetics)
hope this helps mate.
and yes as @Discretepete2676 mentioned that will be the issue more than likely.
when you get a cam if you start a thread under hydro il be more than happy to help you grow them
