35-40 days flowering,major yellowing+some purple

This Outdoor plant has been flowering Since about end of July,I water it every second day, nd i Use a 24-8-16 mg,every week,It Gets sunlight alday long.This is my first time growing,Alot of the leaves have been yellowing,I trimed a bunch of dead ones off before I took the pics, and some of the leaves are turning purple.Anyone have any suggestions so i can fix this?..each day it seems like more yellow leaves appear.Alrite thanks, RENO---------.

You are going to have yellowing leaves at this point...I don't know about the purple,but the plant looks healthy. BTW... your flowering dude. Change over to a flowering fert,and if I were you I would flush with a couple gallons of water b4 using the new fert. Hope that helps

yeah im tryn to get a 20-20-20

Make a cheap little cover out of black plastic and cover it from 8pm to 8am. That'll force it into flower.

na. you want a higher phosphorus nute. the purple is nothing, i like it. its usualy from low temps at night, it`s a pheno of the plant. also may be stress related but dont worry about it.
and yes flush the shit out of them. that mg is nasty stuff. to strong and salts up easy

Yea, I would use something heavier in P than a 20-20-20.
I personally am just using the most available thing which is a 10-30-10.
Some use like5-50-8 or something like that with a crazy high amount of P. At any rate you are heavy flowering at this point( prolly 3-4 weeks) so I wouldnt mess with any covers or anything. I would get your nutes straight for better budding tho. Also I had the purple STEMS in the early spring on mine but not in the leaves. Google it dude, its sure to comeback as either cold related or a macro defficiency. Either way the girl looks healthy. Peace
