Unfortunately I'm not keen enough to mark photos up on my phone. Just top it then leave the node you just topped and the one below it. This will make it grow in 4 cardinal directions. Wait a bit to clean the bottom up below your 4 cardinals, and let it just recover for a bit. Then from there you can either top your 4 again to make 8 or you can just guide the 4 away from the center of the pot and let the secondary branches from those branch out and guide everything up into your trellis. One top per square. Once you have 1 top per square let them get about 2 or 3 inches above the net and flip. Then throw a second screen up after stretch to hold everything up. When you install the second net clean below the first net up, and look down on your plant from above and cut out any huge fans that block light from penetrating deeper into the canopy. The idea for the top to bottom defoliation is just to expose bud sites. Then just let her go to finish
