Yet another newbie ‘mato grower

So my first run of planting tomatoes in my GardenCube started in December, and I've since transplanted those to coco, and they are still growing, but I think I watched too many videos and maybe I pruned them too much or not enough, but either way, they haven't yielded one tomato yet…my hope is that when I transplant them outside (zone 7a is not cooperating, with these cold ass nights!) they'll start to produce. In the meantime, I planted a variety of tomato seeds this time (grape, beefsteak, Roma, , and I haven't pruned one leaf. I know I can't keep all these plants in the gardencube, but they've been doing so well, I'm reluctant to make any changes. Should I? What say you, pro growers?
