What's up garrath. So I'm also doin DWC in 5 gallon buckets. Now ph does tend to shift up or down when in dwc. Also the brand of nutrients can also have a effect on how much your ph will drift. A . Shouldn't be bad its when the next time u check and its at like a 3 or 4. I check my ph every morning and night and adjust accordingly. I GH ph up and down. But def check your nutrient brand cause it will tell u if it will drift or just ask ur local guy/girl at ur local hydro store about ph drift in nutrients. Hope all is well.

One more quick point - ~5 gallons of water is usually not enough to 'hold', or stabilize the PH - i.e. you're more likely to see drift the less water you have. Using 25-30 gallons, we see a drift of one or two 0.x every 1-3 days. When we were using 15-20 gallon res. we saw 2 to 5 0.x drift every day or two, and when we were using a 75 gallon res we'd only see maybe 1 0.x drift a week.

Have you checked the medium for salt buildup? This will drastically drop your pH and keep it down no matter what you try to do, and you will have to flush the medium clean.
