ph dropping in flower?

[me myyself and I]

I was under the impression that my ph should rise if my plants are feeding correclty, but my ph seems to be dropping from5.8 to the 5.2 to 4.5 range.
I ve been adding fresh water that comes outta the tap at about 8.0 or so, to bring the ph back up in the mornings. cant seem to find anything that covers this. can anyone tell my this is occouring?
thanks

Sometimes a plant will lower the pH itself when fighting off a disease or virus.

What's the ppm's of your nutes currently?

pH that drops consistently is usually a result of too high a concentration of nutrients

hmmm, that might explain it cmd420, im gonna knock the ppms down a bit, right now im at about 1600ppms, and about 8 weeks in, will see what happens.
thanks for the help

1600ppm is most probably too high
