How much to trim my bush?

because it is so tightly configured, you probably want to remove a lot of lower axilla. Otherwise it'll just grow into itself and be a giant disease vector. If you want that many vertical colas, you need to spread it out more. After flip (or an auto entering flower), they grow a significant amount more.. neeed to imagine how much growth will occur over 4 weeks, which only increases in speed over time.. exponential growth rate vs linear growth rate (some limitations/ceilings for that but at this point, true still as long as not overgrown for pot and light). you don't want more than 2-3 colas per sq ft... all it does is make smaller, larfier buds a higher proportion of total flower mass. too many mouths. Your light and local environment can support good growth of X grams per sq ft. More colas than necessary won't improve yield.. it'll just make a larger percentage shittier buds. the weight will be similar. Light = weight. how you shape the plant will impact distribution. (common sense - too few colas will not maximize yield, but we are looking at opposite end of spectrum, here).
