Hi
@Vega0284! I usually wait for the 5th node to appear, then I TOP/FIM at the 3rd node. Waiting to see the 5th node is a good way to speed up the recovery process and the new growth from the 3rd node should develop quickly with vigorous growth. Plus, this is an opportunity to make some clones if the TOPped part is tall enough. Hope this will help, happy growing 👊
