HYDRO Dwc ph falling during bloom

[Rj420]

This is my 4th grow using a dwc hydro system and every time a few weeks into bloom my ph starts dropping. Has anyone else experienced this? Any suggestions on why? Do I just ph up my reservoir to keep it in range? Changing the reservoir totally only seems to keep the ph good for about 2 days. My past grows have yielded decent crops, but I just wonder if they could be better yields if I could stabilize my ph better. I’m using advanced nutrients and orca microbes in my res. 600w hps light

I have the same issue with my hydro set-up. In flower mine use about a gallon of water every 2 days. I adjust the ph of what I add. Seems to work ok.

Howdy Rj420, The pH levels will change as the nutrients are taken up by the plants, just do as Eliot Pryor said, keep the 'top off' water adjusted (as well as the feed water) and let them do their thing. I check the drainage pH level (when I feed them) just to keep tabs on the plants consumption and condition.
