Just started using an auto watering/nute system and I’m finding that my ph rises significantly within a day growing in coco and starting my ph about 5.6 within a day it’s at 6.3 is this normal and can I control it other than using ph down every day. ---

Normal based on the hardness of your water. Ph down everyday is acceptable, or you can let the ph wander a bit. You could add aeration to the water, and it probably would help. ---

Aeration will likely cause greater ph swings. How large is your res? Increasing the size would likely slow it down some. ---

Try a product called Torus PerfectPH, it is a gadget you drop in your rez and it keeps ph within an acceptable range. ---

It has a cover ? Uncovered gets swings from light and dust and cats. Ok the cats part may not be true but the rest is. ---

Great product if you use in a reservoir 👍🏻 Chokes the roots of used directly in the grow vessel (Like a bubble bucket). The unit is kinda bulky ---

I use it directly in the bucket (no rez) and have no problem with roots.
