🚨Cannabis Grow Problemsby VegHeadSeedling3mo ago

PH keeps dropping in my DWC reservoir

Running DWC hydro and my pH drops from 5.8 to 4.5 within 24 hours. Constantly adjusting. Using General Hydro pH Up but it won't stay. What's causing this?

Had this exact issue last grow. What fixed it for me was flushing with pH'd water and letting the soil dry out before feeding again at half strength.

Post a picture if you can — hard to diagnose without seeing the actual damage pattern. But from your description, I'd guess pH-related lockout.
