New to hydro - stupid question

[LazyRookie]

Im doing a hydro grow for the first time and i have a question
which is prolly a stupid one....

If the nutrient scheme tells me to add 4ml nutrients pr Liter water, and my hydro container contains 31 Liters, do i then add 31 x 4ml ?
that seems abit over the top ?

Or is it 4 ml pr liter water i add to the tank exclusive the 31 L thats allready in there?

how am i suppose to "read" this?

Thanks in advance

G.H> nutes with the lucas formula 0-8-16 ml/gal grow-micro-bloom is what I used for my first hydro endeavor. So that's 48ml micro and 96ml bloom for a six gallon res .

hey there rookie- your math is right, but in hydro i mix according to the reading on my ec/ph meter. different growth stages require different strength nutes

Your saying "your math is right" but i stated 2 situations so which one is the
correct one?
