Potassium def? Or something else?

[Slothman94]

My Blueberry plant is in its 5th week of flower and seemed to be going well untill I saw this marks on these leaves near the bud sites. Purple spots that start at the tips of the leaf? Im guessing that it might be potassium def but then the description for the blueberry seeds I bought was that it blue and purple hues appear in flowering, so im not sure which one it is because I dont really have much experience as its my first grow. Could it also be something to do with cold temps?
Whats your guys opinion? thanks Oh by the way sorry if the photos come out sideways, I rotate them but when I upload them they just go back to normal

I wouldnt worry about it,they look great. I have a purple strain and when it first starts changing color its similar to that,little specks at first. The leaves look a little yellow though which could be a slight nitrogen deficiency,but that could be light bleaching too,either way this late in flower its probably no biggie,just keep feeding them however you have been. Congrats,looks like it will be some nice smoke.

It does look a little like p def Give it a good feed and it should look a little better, i don't know about the blueberry changing the colors of the leaves like that so i don't know about that.

- also i think the buds are meant to get the purple hue not the leaves, but i could be wrong.

Nah its quite common for the leaves to change color as well,there arent that many strains where only the bud turns purple and the leaves stay green
