Hey bear, a couple of things...
I mix my nutes in a 1gal pitcher with about 6 cups of water, using my cordless drill and plastic paint stirrer. Add to the reservoir once thoroughly dissolved. First I do the calmag+ by itself and dump in the reservoir. Then I mix the rest of the greenleaf nutes all together and dump that into the reservoir. There is a separate pump in the bottom of the reservoir that runs 24/7, keeping everything mixed, moving and aerated.
I don't use drippers bc they clog; just wide open 1/4 inch tubes to each plant.
Loop the trunk line back to the reservoir with a valve on it that can be opened and closed to increase or decrease pressure at the drippers (or in my case just open 1/4" tubes). You've already seen the 1/4" valves I use on ea lead.
Don't forget my anti-siphon hack if your reservoir level is higher than your plants
