Yea I guess really that was the main consideration, just shifting the yield over to a more orderly set of colas vs the rando stem sizes that seem to happen by just doing LST and not trimming as much. Definitely a visible correlation between stem density and bud size. I left a lot of those smaller branches on there and did not prune them but I will be this time. With that theres just the consideration of filling out the canopy, etc.I agree, you have a lot to be proud of here. This wasn't a super simple setup either and you made it work.
Don't worry too much about changing things up. You have a working formula, repeat the process a few times and get the kinks worked out before you change things.
Also topping more won't necessarily increase your bud size, taking out lower branches/nodes along the branch will. Think of it as redirecting the energy from the stuff you take out to the stuff that is left.
Something you can do to help any lower buds finish that might not be getting all the light they need is a few days before you harvest cut off all fan leaves. This will help alot of those unfinished lower buds you find get a little nicer. You can also just harvest your bigger colas and let the smaller stuff sit on the plant for another couple days to finish.
When you top multiple times, how many nodes up would you top again? First pass Ive been topping the 6th node but I did not do multiple tops the first run just to keep things simpler. I am assuming you would want the branch structures as close to the main stalk as possible so probably top first node up each time for each subsequent top.
I still plan to use the scrog to assist in the flattening of the canopy. Only change this time is multiple topping and some added trimming and better environment controls. Especially now that we enter the cooler months the room is just going to be much easier to manage temp-wise. Plus having a nice dehumidifer.
