I'm dealing with something similar. I noticed above 1 of my fan leafs that there's no node/shoot above it. I let it grow up. And well. I wish I didn't now. 8 sets of fan leafs 16 nodes was meant to have I ended up with 16fan leafs ye, and missing 5 nodes. So, 2 ur answer. I do forecast more mutos. Any shoots with no fan leafs, if there's any there. Remove the ones with no fan leafs to support their growth. Shes young and healthy so keep pushing along and learn away. This is part of growing.
