1 ec meter tell you the ppm of solution
you need a base point to start
you need to keep track of it
It would be like driving a car with out a steering wheel. The whole idea of hydro is speed.
Now your going to need a new door for the closet , they way you can cut out a vents top and bottom and add fans to push air. You will also need light traps so inside light does ot show off you lights. You will need
The reason you want a new door as your going to paint it flat white and black on the edges, along with insulation strips to prevent light from getting in or out, the same with bugs
Also you will need some way of killing the great smell of THE BUDS.
The buds will smell up the house in a few hours.
The PH meter is important, the more it cost the usualy the better.
You will also need a tempature vent with a controler. Plants usualy like about 90 d.f.
I suggest you do a lot more reading ,try sharprubberduck.net,, not net not com.
I only have been growing a few decades + and still learning.
A man with one seed knows it all a man with a 1000 plants want to know more.

PS
Remember to clone once you figured out the females
