should i flip

looks to be about half the scrog, so it should fill in the rest, sure. In future i'd try to train the canopy into a rectagular/oblong shape from the start so it can spread out evenly in the footprint you need to fill, otherwise it's more difficult to keep it level filling in the much larger gaps on one axis or end up having to prune shit off on the other axis. first couple runs of using a horizontal trellis just takes a little trial and error to reduce wasted time and effort getting to the same end point. helps visualize when you need to flip too, so that becomes clockwork... simply count squares... anyway take a picture at flip, see how it goes, then adjust the plant for next time to avoid any hassles or problems you ran into. you need 2.5-3 colas per sq ft... going beyond that doesn't add to yield... just distributes the same mass over more bud sites. having an end goal of X colas per plant helps the planning process. 9sq ft is good anywhere between 20-30 colas, give or take. These numbers are fluid.. some plants are bulkier than others and should be on the lower end of that range... talk lanky stuff might be better toward the high end. unless you are growing from seed, you merely pick something that works well for them all and hope for the best.
