nute prob one plant ebb & flow

it is a bit strange because just one of the plants in my micro ebb and flow grow look deficient. the leafs some curled a bit down and others a bit up. its strange because i would imagine all plants would have the same prob. I have a feeling it is too much N. two reasons.
1. i mix lots of nutes together. i am in the process of designing my own little feeding schedule using different nutes from different companies. i just pick the products i like best. the only thing i think i might have fed them too much of is N.
2. this plant is stretching the most and has the least pre-flowers.
at first i thought mag so i sprayed with cal-mag earlier today. i think that was a mistake especially because it has N in it. oops.
here is some pics. let me know what you guys think.
thanks!
these few leaves are the only prob i am having now. you can see the prob plant in the back right corner.

can you provide more info on how the plants have been treated? are you mixing nutes before dilution? ph? brand of nutes? how often do you flood? ... anything you can provide would help diagnose...

gh 3 part some cal-mag, fulic acid, sweet, silca, flora blend, flora plus, right now the ec is about 1.3, 13 days into flower, very small amount of kool bloom.
ph i let it drift between around 5.8-6.3
the wierd thing is its just on one plant.
i have slowly been increasing the floods. i flood when it feels right. i just make sure my ec stays constant and my ph drifts slowly up.
the pic is the best i can offer
i think its just about time to change the res. its been 10 days now. i am going to start decreasing the N slowly. i prob wont add fulic acid anymore. i might start adding some karma (that has some fulic acid in it) after i do the math and make sure my nute ratios are in range.
i believe its just the nutes in the res acting up. I just noticed how long its been since i changed the res. i usually clean it out every week or so.
but just from those pics just curious what peoples thoughts would be from the way those leaves look.
when i run out of my gh 3 part i will switch over to botanicare pure blend pro.
and since it is just that one plant i watched the table flood and it kind of leaned towards it, so i think it might be flooding just that plant with used nasty drifted ph water (that kicks it near it till next cycle) but i dont know.

anyones opinion on the way those leaves look would be great. i already know how to fix it, (flush new nutes, been 10 days) i just want to get good at looking at leaves and trying to figure out what there lacking. cause i am not that great at it right now.
the first two leaves look like something different than the third.
any opinions?

your ph is way to high for flowering. while in veg 5.8 - 6.2 is acceptable but in flower you should be shooting for 5.3.- 5.5

what nutrients do you use?
whats your hydro style?
Ever since I sarted using more organic additives I felt the ph does great where i have it.
I always would have magnesium problems when it starts getting lower than 5.5

(pretend like the only info you have is picture, and leaves are bent upward, growth is weak, and the fucker is stretching more than the rest) (forget my growing style ph, light, ec,)
my goal is to look at a plant and get better at learning what it is telling me. I mean the res was not changed for 10 days and its only 10gal. so it is lacking something. i did already fix the prob. but i still want to learn.
from pic would you still say ph is off? or say it is, by the pic what nutrients is it having trouble obsorbing since it is off?
