Prunus Yoshino, leaves developing red tinge?

[logjam]

Hey everyone! I’ve had this sapling for about half a year it’s been doing very well. I’m in zone 6 and leaves are developing a slight red tinge and one even has a spot that popped up this morning…. Will attach photos. Any advice of what could be the stressor and how to address it? Thanks!

Looks healthy, probably taking on summer color.

This being kept inside?

No, took inside to water and fertilize and snapped photos then. Should I bring it in for the summer months maybe?

No, keep it out. Ans please put your location in your profile. It can help a lot with this and future questions you may have. The red tinge is common in my area in mid to late summer.

Outside 24/7/365. You wil have to find a place outside to overwinter the tree this winter. It needs a winter dormancy that cannot be provided indoors
