Defency or strain trait?

[Why Doe]

Couldn't find any answers on this in my last grow, growing another blueberry and it's doing the exact same thing but this time it's doing it much earlier in flower. Leaves changing a Maroon/purple color. I'm thinking it's the strain but just want to be sure.

Just genetics bro

That's what I was thinking, hard to tell when my plant is having problems when a lot of the leaves are this color lol

I imagine it's not getting real cold around them at night is it? I had a batch of blueberry Kush that was outdoor, and as soon as the night temps got cold, the leaves looked just like that.

It's indoor and it dosent get cold. Too hot? Maybe. Laser thermometer on the leaves is sometimes 90 degrees.
