Question bout ph down

You can without problem, just make sure the pH of the runoff isn't too low.

yes with Citation.. If your using soil.. I recommend just using water and nutrients as is.. Soil that is peat moss based is generally acidic to begin with so why Buffer down when the soil does it for you?. And if your in hydroponics of some variety.. A lot of considerations should be made about Ph. Ie. You wanna balance out the ph between 5.8-6.5 and not set it at one static number.. Plants prefer variance and they put effort into balancing themselves out. So if you run in and change the Ph to 5.8 every time it goes out.. You can be working against your plants. In my experience after a certain point you should be using very little to no ph buffers if your growing in hydroponics. As you can balance out your PH a lot better with Water and nutrients then by adding buffers. We adjust the ph to allow the plant to intake nutrients that it can not intake if the ph is out of range.. Lower Ph is much worse then a higher ph. Ie a ph of 5 will show damage and a ph of 8 may look like a underwatering situation.. PH is poorly understand by a lot of growers and although it is a super important perimeter there are some considerations to be made.. Not all growing mediums are the same.. Different nutrients do different things to ph.. Let's just say there are TONS of little old ladies growing big plants in their gardens and they are not checking the ph.. And they don't really need to because little old ladies grow in peat moss based growing mediums. At least in North America anyway.

Sure. 👌
