Blue roots -DWC

[YYCannabis]

Yesterday I did a full water change on my 4 plants. Today when I went to check the pH I noticed one of the girls has blue roots. Approx 10% of the roots. Same blue color as the nutes, but everything was mixed very very well. That rules out that the nutes were concentrated on a side wall or the bottom of the pail.

Is there something I should do?

I've found over time your roots will get "dyed" by your nute solution, esp if it has a noticeable color. Mine is a red color so my roots tend to turn brownish red. Juts make sure you dont have root rot, but that looks and smells different. If it's the same color as your nute solution but healthy looking i dont see a cause for concern. If roots start getting slimy and look rotten then you got a problem

Ditto what Tersky says: and it also could be the roots absorbing more of one salt at a specific pH...

Thanks for the responses. I just checked them again and the blue is not as noticeable.

This plant is the runt of the litter. Here’s a pic of the runt and her big sister. Both are the same strain, but one is definitely a different phenotype or is just stunted. No preflower buds anywhere, but her 3 sisters have tiny flower buds with pistols growing.

Big Sis has 10 branch nodes...Little Runt has only 6-7 branch nodes. All seeds were germinated/planted/fed/lighted the same. (July 24)

Weird? Right?!
