Crop King Gelato 48, my first grow.

So this is where I’m confused. Backstory is I topped and mainlined 3 of the trees and one is a “control” tree just to see what happens. So I got the canopy relatively even, for the main lines trees I have 8 mains that were LST to get in the shape that they are. So where I am confused is the lower colas? Coming in on each of the 8 mainlined trees, am I attempting to keep those same height as the main cola? Pic in this week pointing out for reference. Or do we just step back from here , keep the mains relatively the same and just let it grow? I planned on a defoliation early next week for the lower part of the plant etc. Below from 6th. Not much going on with the plants other than weaving and tucking for the scrog and just keeping them happy. Second pic is the start of the watering system I’m trying to set up, six inch watering rings with lines ran out to a 2 gallon tank. So far for the four plants I have needed to use six gallons of water but I notice there is a bit less in my collection trays. I need to watch this and maybe need to prep a fourth two gallon tank to make sure they have enough. Watering also moved up a day, feeding was every Mon/Thurs , now it is Sun/Wed. last week I noticed by Monday all of the plants leaves were dropping a bit, the indicator tree so far is what was the runt tree, it appears to be pulling slightly more water (it is massive by now with how much it is bent over and Scrooge’s through the net.) so I have been keeping an eye on her as that indicator for watering.
