I thought about that. I’m in coco so I don’t even bother checking the pH of the run off. After everything is mixed up, the pH settles at 6.2. I water by hand every day, and mix fresh nutes daily also.
100% this ^^^ and adding to @Skybound if using silicate such as potassium silicate and not silicon like silicon dioxide the you absolutely need to add it first and let it mix for 20-30mim at a high ph (it will raise ph above 9 or higher absolutely) then ph it down after mixing to 6.5 before adding your nutrients to prevent precipitate. After adding nutes being the PH down to his suggested ranges... absolutely agree here.
Hey @Skybound I can't help but feel we met somewhere before.. online but possibly before I was a mod? Anyhow welcome to the farm and glad to have ya.
For some reason, I always feel if I have to add pH up, or down, that I did something wrong lol! This is a good idea though. Will lower it when I mix fresh nutes later tonight.
I feel like I know that handle so we'll cause I've read his post's so many times
Curious what your EC going in is? Elemental ppm appears to be a guess at best. I've gotten dark green leaves using Jack's and all I had to do was dial down the EC a few points because i was feeding too much.
I wish it was MORE alkaline, I haven't been able pull my root zone out of 5ish pH for over a month, doubt I will by the end.
I’m in coco, and from what I’ve read, and been told, is that it’s pointless to test the run off pH of coco, because the coco will buffer the rhizosphere pH to within proper ranges, but the runoff pH will be all over the place, thus not giving a proper reading. What’s everyone’s take on this?
Yeah, not using coco but I've heard the same about organic, but how do you gauge otherwise? If you wait for the plant to show in a lot of cases its too late.
Expand the coco with calcium nitrate to buffer. Feed to runoff to get rid of the sodium content.
Been doing that for 4 years now lol!
Why? You can do 2:1 K:Ca for healthy plants if needed.
Okay. Maybe overthinking it a little. I just figured since coco is supposed to release K, I didn’t want to over do it. That and the fact I’m using Protekt right now as my source of Si, and it adds another 35 ppm of K. That would put me at 205 ppm of K! To much don’t you think?
