Variegated mulberry?

[Just1More]

Got these Tice mulberry cuttings and they have been growing good for maybe a little over a month. Out of nowhere I see the top shoot coming in with different colors on its leaves. Not sure if I’m doing something wrong or if I just got really lucky! Please someone tell me what’s going on here. The bottom shoot looks normal and so does both the other cuttings. I’d assume they were all from the same tree.

Can micronutrient deficiency be ruled out?

Are they rooted? Sometimes they will put out good growth and then die if not rooted. Looks like a N deficiency though. I might not fertilize if they haven't rooted yet.

They seem to all be rooted. But out of the 7 varieties I got these were the slowest. I used coco coir, perlite, vermiculite, sand, and maybe some black cow. Is there anything I could put on it to make sure it’s not N deficient?

Not ruling out anything yet. How would I fix the deficiency?

You can mist the leaves with dilute water soluble fertilizer and see if they get darker.
