LST both plants.
Plant 3 has healed well from the topping and is back up in full swing. Looks like 4-5 main colas currently, but we'll see how that plays out
Plant 4 has stopped producing tri-branch nodes. The first 2 sets of branches has 3, but now they're back to normal. The main cola keeps growing at an angle, and the leaves coming out of the very top appear to stick together a little more so I'm not sure what's going on there but it'll be interesting to see what's up with this plant.
