Yellow and purpling leaves

[Pawnee]

Ran these genetics last harvest with great success. Took 12 clones which have also done great up until about week 4ish of flower. I have bumped nuits to full strength at week 4 which I believe we are getting in 5 n half or when 6 now. Was really weird that it started in the center of the canopy with 4 plants then spread but still the outer canopy still look great and healthy. My last harvest didn't look like this till I started flushing. Running coco and perlite, humbolt nutrients, ph 6.1 to 6.3. Temps are great between 75and 78

The line of humbolt I got has it yes. I'm leaning toward a phosphorus deficiency. I used general hydroponics 3 basic nuits plus their bloom last harvest with lots of success. I still have some left maybe I should just finish this run with general hydroponics.
