One question I have is the PH is dropping each night from 5.8 ish to around 5.2 ish. All roots are very white, water temp is avg of 68 RH is around 60. Is PH dropping normal or what should I be looking for?



Thanks

Your nutrient strength is too high and your plant is drinking more water then nutrients, I would reduce your nutrient strength. When your pH rises and your PPM drop your plant is drinking more nutrient then water and you should slightly increase the nutrient strength. When your pH drops and your PPM rise your plant is drinking more water then nutrients and you should slightly decrease your nutrient strength. You are trying to aim to supply the plant with no more/ no less nutrient then the plant is currently using, when you achieve this balance your pH will remain mostly stable.
