need some HELP, please!

I've got a "friend"... and he has a problem...

Lets assume, hypothetically, this is the set-up: GrapeStomper OG, 2nd week of flower, grown in Light Warrior with a little CoCo coir added, 250HPS, TechnaFlora's Recipe for Success at 100% strength, pH is all good and so are the temps. Pictures are a problem, NO camera.

Here's the deal... It all started with the top half of the plant, only the top half fan leaves, they began to "eagle-claw" about a week ago... some on RIU say its too much heat or light? I don't think so with only a 250HPS. Some others said the feed formula was too strong? My "friend" will try reducing the feed strength to half on the upcoming feed.
Now... along with the "eagle-clawing" of the top half fan leaves, my "friend" has noticed that the very top-most 2 sets of fan leaves are an uneven green... mostly dark green, with lighter green in between leaf margins and in the very center of the leaf its almost a lime green.
What could this be???

I hope I've done justice describing this issue, my "friend" could really use some advice.

full strength feed = nutrient burn

Too close to the light can = too hot even with a 250w HPS

Thats it...? c'mon, my "friend" needs some help

Pretty vague. And not correct.

Most nutrients are designed around marijuana whether or not they say or not. And as such have been tested on these plants, guarenteed in those companies labs. Just like anything else it depends on the strain.

I talked to my "friend"... It seems to be getting worse.

Now the new growth is that lime yellow-green color in the center of the leaves.

Could be calcium deficiency. Are you feed tap water or distilled?

Could be sulfur deficiency. Could be nitrogen witout knowing the rest of the plant.

Not to be an ass, but honestly pictures are a must for these things for two main reasons. One nobody wants to READ your VISUAL problem. Two it is incredibly hard to include all the information none the less in a readable amount of text.

Shitty old camera phones take pictures, give us one please and we will throw you more answers then you know what to do with.

I will do my best on getting some pictures... from my "friend", even if it is an old camera phone
