Purpleing on leaves

[Bluugrss]

Soil ph is 6.5
Plant seems to be doing well.....except for the purple. Im thinking phosphorus ...but I've been feeding the plant tiger bloom at half the recommended dose once weekly.
I gave it a full dose last feeding and burnt the tips.....and still the purple seems to be getting worse.

what strain? Cool nights? normal color expression is likely behind this, not a P defc.,..but if you got some burn, go easy on the feeds...

The strain is "autoberry" from msnl.
Temps at night are 70°f and around 80°in the day.
I've backed off the feed since the burnt tips.....time will tell.

normal coloration then, no worries! BB cultivars can get very deep colors... here's Maine's Own Blueberry -->

not trying to steal the thread but I have something like this also. It is happening to leaves that are a certain distance away from the light. The leaves that were closer were light burned. It happened on a BB, GG, Critical Purple is pictured, but the northern lights just turned white with no purple. It's pretty neat for sure.

I'm curious, what light, and how far from the plant tops?

I was curious also. The light was built for someone and the specs arent all there. I do know it is red, blue, and some UV for sure. There were no instructions. I was reading that purple in plants is from Anthocyanin which is absorbed inbetween the red and blue spectrums according to this chart. I haven't researched any further as the light worked very well for me.
