EI and Hidropony?!? - Aquarium Plants

Hi, some friends and I are trying to make an hidroponic system and as a basic fertilizer solution we're trying to use the EI scheme with KNO3, KH2PO4, K2SO4, Chellated Fe and Micronutrients Mix...
Is it possible to use the same scheme of the EI in this system or it would not be good?
Thanks!

No, you should go much richer in Hydroponic systems(10X or so). Also, you can use NH4 based ferts.

Thanks Tom!
One mure dumb question...

What is the ideal value of pH, gH and kh on hidroponic systems?
Thanks again!

Hi Tom!
What is the ideal range of pH, KH en GH on this system?!?

Thank you!

Thank you!

pH is generally in the 5's.
KH is generally best low as possible, GH, that is just Ca and Mg, b9oth plant nutrients , so as high as most hydroponic literature suggest.

You are only dealing with roots, so the nutrients can be much higher.

Most Hydropinic sites have plenty of info on making solutions for growing a variety of plants.

I'd use those if I where you.
