How to plumb a 4 pot auto feed setup

Hey everyone so I’m going over how to setup my auto feed system. it consists of a 100L res and inline pump to feed 4x irrigation manifolds. My thinking is to run a line up the centre and 4 way tee off to first 2 pots and a 3way tee feeding the second 2 and use taps at each pot to adjust/equalize flow to each pot. Running off a digital timer feed twice a day.I’m sure this approach is fraught with problems. Is anyone able to give me some insight or know of a better approach.
Thanks
