Ph Falling but EC is Stable? (Yet another ppm/ph question)

So, I'm in my last weeks of flowering (around week9 ) and I've been having this issue for a little while. It only began a few weeks after the flip to 12/12 and buds started showing. As the title suggests, while my ph is falling between .2 and .5 a day, my ppms are staying the same. My first thought was root rot, however I run hydroguard and keep the water at a constant 66-68. Not to mention just looking at the roots themselves, which show no sign of such. I know that ph up and EC down means plants are wanting more nutrients, and vice versa means too much nutrients, however I've been able to find very little information as to reasons and causes for the ph to fall yet ppm remain the same (about 1050). I can of course keep adding tons of ph up, but this cannot be good for my plants roots so I'd really like to figure this issue out before it comes time to flush. I've heard that it is natural for the ph to fall while in flowering in DWC, however something doesn't seem natural about this. Thanks to any and all who read this, any input would be greatly appreciated!

Is the water level dropping?

And what feed are you using? In the title you say EC dropping yet you gave a ppm figure. Dont use PPM. EC = EC. PPM = whatever the fuck it wants to be
