newbie nitrogen problem

first off let me say thanks for reading this post and any input is greatly apreciated.

so, its week 4 of flower and seemingly over the course 2 nights the girls have gone light green/yellow almost entirely. I belive this is classic nitrogen def. but too early to be normal. so... I gave half of them more nutes and the other half fresh water... (idk what im doing lol.:wall:)

I was hoping someone could critique my routine, because I would like to determin the cause.
anyways..

heres some info

1 meter tall in 6 liter pots (i pulled one out and i dont think its bound but its close)
600w hps 12/12
SUNSHINE mix#4
nutes: Advanced micro, grow, bloom, b52, big bud, and bud candy
day time 75-80F 60% humidity
night time 60-70F 65% humidity

so my nute mix is always going in at 6.3 and then run off is like 6.5 normaly. I have 2 soil ph testers and they both read over 7.0 and somtimes closer to 8.0!!! I cant seem to get the sunshine mix ph to drop without flushing it with with like 40 liters of ph'd water (which takes like 3 hours per pot). But Ive read 7.0 is a good ph for this medium.

I water once a week or when the sunshine mix is dry, it is almost always exactly 7 days, and I add nutes every other watering, so once every 2 weeks they are fed.

this is my second go around, and the first time they did fine, with twice the amount of nutes with every watering.

thanks a bunch!!

p.s. sorry if i forgot anything, let me know and ill fill in the blanks! :D
