Ph dropping, EC rising, water level dropping conflicting advice

Ok cool. I kinda figured there would have to be a sweet spot no matter the res size. I would worry a lot less if ph and ppm stayed more stable thru a few days instead of every 2 days having to do a res change just to stabilize.

when i did single buckets, my pH almost always went up daily. i would set at 5.5 and when it hit 6.1, then add ph down.

i was more worried when ph went down. that was usually a bad sign.

and i prefer my ppm to drop daily which told me that the plant was eating. if ppm stays the same, that "could" be a nute lockout situation or it could be that your ppm was exactly what the plant wants.
