Hi.
So you see the 1st set. The one with the 1 leafs. I remove that normal "the leafs and nodes above them "knots" as they nearly all the time runtz out of all your sets of nodes.
So, upon removing the 1st set and the top you'll be left with 4. Cut above the 4 making sure not to cut the node (will be above the leafs stem where it meets the main plants stem. So you'll be fully removing no 6 and cutting below that, (it'll be no 5 if you remove the 1st set) leaving you with 4 sets, 8 nodes to shape
You'll be able to apply LST also. Id kinda not leave it any longer. As once you to it. All upwards used energy to make the plant grow will be diverted to your nodes.
Good Growing
