Roots look good, and using tap water 170ppm.
Using AN Connoiseur line.

How does the plant look? Do you have a concern aside from the pH reading?

What do you use to check pH?

does it seem they are drinking a lot of water? if so, your ppm goes up which causes your pH to drop. if the grow area is warm, maybe you're seeing a lot of evaporation taking place. the water will evaporate out but nutrients won't. this will also raise your ppm and lower your pH.

Blue labs combo ph ppm meter. I calibrate the meter once a month and then I have a cheaper meter I use to verify that meters reading.

those look great. don't worry. just finish them, reduce the fert about one week before you chop them. you don't want to consume the fert.
