yes that was a ak47 i grew last year.
I grew ak a couple years back, great weed but couldn't keep a mother she just flowered no matter how long you left the lights on. Called the seed company and they told me alot of people were having problem, must have been a bad batch of seeds. Anyways what was your dried yield off that plant in the pic?

the bluish leaf indicates too much nitrogen i'm 100% sure of that

Nitrogen Deficiencies
"Plants will exhibit lack of vigor, slow growth and will be weak and stunted. Quality and yield will be significantly reduced. Older leaves become yellow (chlorotic) from lack of chlorophyll. Deficient plants will exhibit uniform light green to yellow on older leaves, these leaves may die and drop. Leaf margins will not curled up noticeably. Chlorosis will eventually spread throughout the plant. Stems, petioles and lower leaf surfaces may turn purple."

Not according to RUI:

I agree with Word. Look overfed all all fronts. Coco is notorious for salt buildup. Good watering habits are a must along with leaching or flushing the medium from time too time during the grow. Look in the stickies, MJ plant problems and cures. You will see that you have a couple of different issues. And I see no sign whatsoever that the lights have caused any of this.

Newbs. Give them sound advice and they argue until you tell them what they want to hear. Listen to Word. He is correct. Fucking seems to be the norm around here anymore.

all the pics are from the tops of the leaves notice the plants aren't light green or yellowing. When they get too much N they turn dark green almost to where they have a bluish tint.

dude i ain't a "newb" and I'm just quoting RUI and what recently happened to me. LOOK AT THE LINK!! And that's a good defense mechanism calling someone a "newb" and I'm arguing because I know i'm right.

I completely agree but the picture of the leaf with the bluish tinge is the odd one out most of the leaves are yellowing from the veins outward....

You blue tone is actually a very dark green. The purple fom a def usually manifests in cooler temps. You obviuosly do not a cool temp problem. Wordz and myself are exactly right. But since you do not want to listen to reason I will tell you what you want to hear. Dude nitrogen def. Up your nutes and feeding schedule. Your 400 watt light has light bleached them at 24 inches. Better move it up.

Honestly it could be anything, but usually when i had a nitro def they started to yellow at the tips and work their way in, that leaf looks like it was burnt by a light, not sayin that's what it is just what it looks like and believe me i have burnt my share of plants lol Make a check list and go through it and that's how you'll figure it out
