Day 50 of flower. Temps through life have been lo...

Flush asap. And then thoroughly let your roots dry and hope you didn't rot anything. More than likely due to over watering. When you flush your leaves will turn yellow all over. That is fine because you're very late in flower and don't need Nitrogen anyways.

Yeah, buddy - you've massively overfed them.... if this was my grow, I'd do a flush ... good luck!

Its not "fading" but burning/dying from being way over fed.

But to heavy handed on feed. But? Even then fade can still happen.. Some phenos (purple names, doesn't always mean purple strains) Its true a more stressless grow? Fade triggers easier but its either got it! Or it doesn't, and yours does not! Just lower the feed. If its soil. A wk even 2 on just enzymes to help uptake. Idk how far you're away from harvest. She's prob ready now. But if you've been feeding from the start. Just feed her water. If she's been on organic nutrients. Just pull ready when you feel up to it. Good

Well, you are half right, but you definitely ignored some obvious salt buildup symptoms along the way, because this sort of dumpster fire doesn't happen over night. Probably fed too much of a lot of things and if you don't have guaranteed analysis labels, it'll be harder to figure out.

Looks like extreme nitrogen toxicity to me.
