@PablosFarm, it is never a good idea to pH up and pH down the same batch of nutrients. If all 3 of them are rising at the same rate then it is something in your water and nutrients. The ro water should help, but a lot of different nutrients don't play well together especially in dwc. I have tried most the popular nutrients over the years and general hydroponics maxi nutrients hold stable for weeks in a healthy system. I have fluctuations if I mix anything with it. If you have cloudy water then something funky is probably growing in your system and a couple tsp of 3% hydrogen peroxide will clear that up. Best of luck with the rest of your grow.
