I'm reaching out because I've noticed some unusual deformities in the leaves of my Washington Navel Orange tree (grafted in September this year), and I'm a bit puzzled about the cause. I've attached a picture for reference.
I'm located in Eastern Europe, so I'm keeping the tree indoors under a full spectrum grow light (SANSI). It's been growing and healing really well, I'm only concerned about the deformed leaves. There seem to be no pest causing the problem.
I would greatly appreciate any advice, tips, or suggestions on how to address this issue and promote the health of my tree.
