i don't stop feeding, but i do taper off, and i think this is where i'd start tapering off. over the next couple of weeks id drop them down to about 200 ppm then stay there till they were finished.
Leaves are dying off I’d like to chop Jan 1st lots of Amber hairs trichs are somewhat milky but hopefully by the 1st itl be ready to chop down I will post another update on Monday
I would wait abit yet.. but that's just me.. it's all about your preference if it's for you.
I notice abit of tip burn and looks like abit to much nitrogen ... really dark leaves are a tell for toxicity which can lead to lock out.. many people mistake magnesium defisioncy when it's phosphate lockout do to to much nitrogen.. your plants arnt bad looking just some little things to tweak.. do a flush with p.h. 6.5 water only the next time they need a feeding after the flush continue with a lite feeding of nutes or run the last week or two with just p.h. water.. it's a preference thing again .... all in all there pretty good but I would wait abit.. maybe two weeks
