That's awesome bro for almost 50oz and not having a even canopy once you dial the room in and understand the stretch of each strain you will kill it even more i think once you get some big yielders and just stick with them and you will pull the two pounds a light yes its a lot to do with training and feeding the right levels at the right time but strains have a lot to do with yield and i think if you find a strain that you love just run that and master it
i know its hard because as a grower we always want to try new smoke and we enjoy watching how other plants grow as growing the same thing can be boring but once you find a strain you love just give it a few runs and you will get better every time as you will know its max levels and you will be able to push her to the limits
Your a skilled grower so whatever you do ill be subbed for the show
