Nutrient disorder please help!!

Something is wrong... My leaves are changing color, starting with the large fan leave. I have checked the sticky with the leaf diagnosis but since this is my first grow id like to hear from some people with experience...What do you think my problem is??

Thanks

I would say mag deficient, prolly due to ph troubles, flush well with correct ph solution. the leaves affected will prolly get worse before they get better. just pay close attention to the new growth. you might want to keep check on runoff ph, it'll give you an idea of whats happening.

agree with no pain. Looks like Mag def but from what who knows?
Whats the medium? What nutes and what ph u keep solution at?

Thanks 4 the quick responses guys!!! I am growing under a 400 w MH in sunshine mix 4 using advanged nutrients 3 part feeding every other day and flushing once a week...and the water im using is tap water ran through a brita filter then ph"d. I checked my runoff ph and i think u guys are right, it was high, I am flushing and adjusting my ph. I guess my final question is what should I expect if things are getting better, are the leaves already affected doomed to die, or can they improve from their current state? should I not worry about the fan leaves affected as long as the flowers are still looking healthy? any and all opinions are appreciated.

Oh, I kid.

Affected leaves will not get better. Your goal, is to stop the progression in it's tracks. It is one of the mobile elements...N, P, K, Mg, or S...cuz the damage is appearing in the oldest growth as the plant cannibalizes that part. Wut is causin it is a different question...a high pH is not the likely culprit. As you kin see, those elements are not affected much by high pH...

Bob you wouldnt peg this ass Mg def?

Not fer sure, no. I am very careful aboot accessin deficiencies. Many times when the plant is deficient, it is not because the element is not available, it is due to some other reason. So if you go addin that element to correct things, you might actually jus be makin it worse. That's why it's important to know wutz bin thrown at the plant already (soil & ferts), to see if that missin element is present. If it should be available, then the problem is usually not from a lack of it. With AN....well, they're jus not wut I would consider reliable.

good shit. Makes perfect sense. Ive coe tot he same conclusion in my grow experience. Defiency for me RARELY if ever means if is not present ( deficient nutrient). Always a ph or nute lock out thing
