Thanks for your response.
In the OP I stated that the nutes are simply - chicken shit tea. I did hit em once with a 1/4 strength dose of bloom nute of 10-54-10, so 2.5-13.5-2.5. This was after the canoeing and yellow however.
The plant is in a greenhouse, and the current temps are typically 65/70 at night - 90/100* peak day. Normal daytime temps are around 85 and about 65% humidity.
I dont water until the pots are light and/or the plant is starting to droop for thirst. but, she was in a 3 gal pot and I was watering about every 3 days or so. I recently transplanted her into a 5 gal pot and the root mass was fairly white with some tanning around the base of the container where they most likely got dry fast due to the drainage holes. She also wasnt what you'd call root-bound, but getting close around the base of the ball.
The Purpling has been visable since it was about a month old. All other plants from the same bunch of seeds, including the male that I never really fed, have some purple (this is why I saved him for pollen), but not as much as this one. She has always been more purple.
As far as N deficiency goes, everything I've read states that N def starts at the leaf TIPS. These start at the leaf BASE. No drying of the tips have been noticed until total chlorosis. Even then, the drying starts anywhere on the leaf. Also, there's no curling of the upper parts the of plant.
