My leaves are turning yellow. Im A first time grower, iv had a number of problems, but up to now, iv over come the problems, but this 1 is baffling me. Im using northen lights auto and theve just started buddind and all of my leaves are turning yellow with some greyish, brownish spots, except the leaves at budding sights are ok. Im sure im either over or under feeding nutrients

Lizard13 ,we need more information, stuff like, what type soil, or coco, your using, how are you feeding-watering them, and with what ?
Are you phing your water, ?What kind of pots your using, What kind of light you using, and how far away it is. That kind of stuff.
You changed anything lately,? Anything you can tell us, will help.They look like big nice plants though.Cfls for a week or two

Got 2 northen lights auto and 2 afgan skunk auto, trying to keep lights 12 inch but growing aT different heights. 1×1×2 tent 4 inch extractor fan which dosent seem to be moving a lot of air which is why im only using 250 hps otherwise it over heats.Comment

That looks similar to what happened to my Northern light autos, but was much later in the bloom with only a few weeks left so I just flushed and watched as all the fan leaves fell off on their own.
I can't confirm if it was nute lockout or not as it was my first grow and made some other mistakes, but when I flushed I did find my EC was almost double what it should have been 1000+ppm. I also use GH trio and follow Campesino guide which I believe is closer to 1/4 strength.

Could very well be locked out, what is your ph out ? I never had any trouble with my NLights autos, they grew good, but they were in Living soil, too.
Flushing is hell on plants, but not that bad when using coco.
You need to check your ph out, and your ec, if you can.
But your gonna be fine, and make it to harvest, but you might have to flush your girls, and get your ph, right first.
