Afghan Kush Ryder - when to harvest?

Hi all,
The pics below show an Afghan Kush Ryder that is getting near the end of it's second month since poking it's head through the soil.

I want to know should i stop feeding nute's yet? and how long left do you think i have left before i can chop? the plants an Afghan Kush Ryder and smells potent, these auto flowering plants are bigger than expected.

no way shes no where near done..... what week of flower are you in?

Looks like she just started flowering! Wait until you get some orange hairs going on atleast!

when about 20 % of your trichs turn amber then your girl is ready

keep feeding nutes untill you have about 75 percent of red hairs,the plant looks like she has not been flowering long.did you use a pk spike.If you had used advanced then that plant would have been swollen now, your next grow swop over to advanced. and you will see 10 times the ammount of bud then you will get of this yeild

hi thanks for the answers.
been flowering for roughly 4-5 weeks now (had 5 days without power during start of flowering which knocked back the plant i think).
flowering under a 125w red cfl and 45w blue cfl.
any tips on getting the plant ready faster? when ordering these i found the manufacturer states they can flower in 56 days from seed, is this true? seems to be about 56 days if not longer. ive noticed a few of my buds have started to turn a tiny amount orange on a few hairs but also heard this can be caused by heat. the heat in theres 20-26 degrees.

cheers

yea its gonna take about 7-10 weeks for full flower, and actually i go 48hrs of darkness before i go into 12/12 so i imagine it cant be that bad for them...

cheers for the help! I am very impressed with the afghan kush ryder. Whats the high like off them?
