Gardening Know How Questions & Answers - https://questions.gardeningknowhow.comI just start my Hydroponic vegetable garden and I note that the pH changes; I start whith pH 5.8 and the next day it is about 6.8. I put the pH down and the next day it is up again. It is normal, or am I doing something wrong? The same thing’s happening on my seedling box where I want low pH. Regards Giuseppe Tondo

This is completely normal for hydroponics. Usually, lower grade nutrients will break down and become unstable, faster than high quality nutrients.
This can be corrected by daily pH adjustments, which was the standard until pharmaceutical grade nutrients for hydroponics came out, or it can be corrected by using good quality pharmaceutical grade nutrients.
They will stay very stable, often for up to 2 weeks, with no pH adjustment necessary.
Here are some articles that will offer more information on hydroponic gardening:
