pH drops 2 tenths and plants turn yellow

[medicalGreenGrower]

for some reason last week i decided a pH of 5.6 was the way to go and all of my plants quickly turned light yellow and any leaves remaining green were light colored as well. i put fresh 5.8 pH nutes in a few days ago and i'm still waiting to see some kind of change. these plants are all in some stage of flower.

this has been a recurring issue for me - the yellowing - and i can't figure out what is wrong. i'm following the instructions from the nute bottles and several hydro books but i haven't had any luck keeping my plants green. even in veg, every time my plants reach week 2 of a 3 week stay, a few of the leaves on each plant turn paper bag brown and are just as stiff over night.

i thought maybe i was using too many different nutes (4 gallons with advanced nutrients sensi A+B to 600ppm
with cal mag, liquid karma, and cannazym bringing the solution to 800 or 1000ppm) but i can't imagine that this is a possibility. i'm running 3X3 rockwool cubes in hydrotron with plants at 10 to 12" when they go to flower. veg is 3 weeks. my pH is now, and was, kept at 5.8.

does anyone have any suggestions on how to beat this problem? thanks.
