How are you taking readings??? If the bubbles are splashing you will get weird readings all over the place. Get a clean cup, dip and put your meter in the cup.

honestly i have been doing DWC for years now and always produce the highest quality with impressive yeilds and i have never checked the ppm once maybe that is do to the nutrient line i run or what but never have once. for the PH i always like to keep it on the lower end like around 5.8 that way it can rise and not do damage. then if i notice it jumps quickly in the week or whenever i see a rise above 6.5 i will add low ph'd water say like 5.0 to my resovoir to keep it from jumping to high. i never add straight up or down into the water though always dilute with water i guess i should have said first that i use a resovoir that leads into a controller that feeds 8 buckets drip system i dont know the type of system u run

In DWC it is normal for your ph to float upwards. I add a drop or 2 of ph down every 3 days or so when I add water. It is also normal for ppm to rise, it means your plants are drinking more water than nutrients. Just add some plain water with no nutrients throughout the week depending on how much they drink. Everything is fine dude!

This boils down to the question of who knows best - the plants or the meters?
