Were you not expecting them to turn purple? The colors are not just limited to the flowers.

Runtz is a purple strain so you will likely see more purple as you go.

I did mention the strain and purpling in my first sentence of my post/
Honestly I’m not sure what strain of Runtz I have. It was sold to me as Runtz, but that seems to mean very little.
In your experience do they all turn purple?

I guess I was expecting the purpling to be more of a fade in, rather than spotting.

The purple tends to be what peeps will breed for but not all plants that can turn purple, will. Aside from genetics, temps can play a large roll in color changing. Something like a 15degree temp swing at night will give you purples. It will likely get darker as the days progress.

Thanks, Docnraq.

My lights out period is never more than 5-6 degree difference.

I would hope with the nute solution that I’m using that phosphorus wouldn’t be a problem.

Can anybody else confirm that this purple spotting is normal shift in color?

I think it was @imSICKkid said that changing your PH to around 10 would also cause colors to come out on the plants.


Thats gotta be rough on the lady.

Don’t know I never tried it. I would imagine it would cause lockout, its been awhile since whoever said it, said it, but I think they were in the late stage of flower.
