Hard to see in picture but looks like it may be potassium deficiency

 

[Why Doe]

Any better?

 

[Imhigh85]

Pretty sure it's the beginning of potassium deficiency I don't know what seed bank you got your blueberry from but most of them don't start turning purple on the leaves were buds until they start getting late into flowering

 

[Why Doe]

What can I buy that has potassium in it? None of my stuff does

 

[Imhigh85]

You might want to go back and check that again it's part of your NPK it should be in all of your nutrients some supplement will not have it but should be in all your main nutrients

 

[Imhigh85]

What is your pH of your water and what is the pH of your runoff just curious trying to figure out exactly what it's called in it

And the K is your Potassium. Is it same temp with lights off or a lot lower? As if the strain prone to it if you get down to low 60s it will turn faster and it kind of looks like that when they do that. Pic of a Blue Widow I had (well still have her grandkids (clones):

later in Flower same plant:

 

[Why Doe]

The runoff has always been over 7, have never been able to get it lower throughout the entire grow. The temp never falls below 73

 

[Imhigh85]

With your runoff being a above 7 it could be calls by the start of salt lock

I do not think it's a K deficiency. Are you seeing anything other than that? Yellowing, wilting, crisp edges? What is your ph, and are you testing the runoff or soil?

 

[Why Doe]

Other then that the plant looks perfectly healthy. I do believe I had nute lockout a couple weeks ago cuz my leaves were drooping but I flushed and the plant perked right up. Needless to say I won't be making the soil mixture again because it will NOT allow me to lower the PH below high 7s

 

[Imhigh85]

I have been doing this for 12 years now I run a dispensary in New Mexico I am pretty positive that the entire problem is due to Salt lock in your soil due to pH this is the most likely reason

I agree. Salts could be way high especially with all the nutes.
Flush and ease back in, add a little calmag. It will be ok.

Other than the purple, are there any other signs of problem?

 

[Blazin Waffle]

I see you said it looks perfect otherwise. If that's the case, it could just be genes.
K.I.S.S.
Live by it. Keep it simple stupid.

Maybe the bloom booster is pulling out later flower traits. If your leaves aren't crispy, and there's no yellow, keep on keeping on!!

 

[Blazin Waffle]

If it looks green and healthy, I wouldn't worry one bit. I'd be attentive for the next week or so, she will let you know.
The more I think about it, the less I feel purple poppin up on a plant with purple genes, is so worrisome lol

 

[Why Doe]

I haven't used the big bug yet, just did though. I will see what happens in a few days

 

[Blazin Waffle]

Just keep an eye on it, be aware of any other changes that might indicate it's more than just pheno

 

[Why Doe]

Maybe there is cause for concern? White bleaching type spots are starting to show up
