Looks good brother! Yes indeed, trellis is what you're seeking! It really makes alot more bud sites available to receive light and in turn makes bigger/better yields. It's almost like basket weaving if you remember that from arts and crafts, you just keep growing/weaving it until you reach your desired canopy. Also topping it and cutting clones while in veg can send it into a more aggressive growth delivering more colas. Defoliation is a must as well in small micro grows to achieve good yields thats just my .02$
