using miracle grow organic natures care soil. Growing mostly auto flowers. Growing under a phlizon 450w. But I only use the Cobb lights at around 250w for seedlings. Ph in at 6.5. I did a slurry test yesterday and it read 5.9. Using house and garden nutrients. I’ve barely fed anything. My tap water sits and bubbles for 24hours before I use it. plus a tiny tiny bit of vitamin c for chloramine. I fed once at 6.8 thinking soil was too acidic but now I’m seeing ph patches. Yellow sort of in the middle. And my seedlings are almost all dying. Please help me. This sucks.

Just a FYI letting tap water sit doesn't do anything.. it used to work a tiny bit on chlorine but on Chloromine it doesn't.. i only use tap water and have for years it doesn't hurt a thing (Do as you like, but just a waste of time)

As far as the plants go, honestly they look like they aren't getting enough nutes and i would drop down to 6.2ish for ph.. but to each their own :)

Thanks for response. I had 800ppm on slurry test on my auto that’s flowering. I’ve grown some amazing buds. But something is causing problems and I can’t figure it out. Idk if it’s a hot batch of soil or what. What should soil ph be at? Is 5.9 low to you? All my seedlings keep turning lime green, yellow, super stunted growth. I can’t figure it out.

Stop phing so low
Once that water hits the nutes in your soil it is going even lower
Ta da I wouldn’t even ph a built soil

What would you recommend for ph? I tried going in at 6.8 because I was wrong my soil at 5.8/ 5.9 and I woke up and see the whiteish patches from ph fluctuation. These are killing me. I just moved and it messed up my mojo.

Not really built dude. Has very minimal nutrients in it. But idk about that because all my seedlings are turning lime green and dying. I’m def not over watering. And I use the weight of the pot to determine how much and when I water. I think I’m okay on that

A slurry test is inaccurate, and ppm coming out of soil is more so. Just water straight from the tap and see what happens

ok man I’ll give that a go on a few of them and see what’s up. Any other suggestions? I just bought coco. I think I’m switching over for grow periods and yield.

Stop checking ph and don’t feed seedlings
You can’t even say “ph” patches”Because by the time you see them the cause was weeks earlier
Just feed them nitrogen and don’t ph
I never do 27E7AEE8-EF24-427D-96E1-C91C6B39CAE0.jpeg

Looks stellar bro what strain is she? Looks a little TK Mints style, Yah I do notice with organic nutes your right its typically best to let the soil adjust to its desired Ph if you keep it inoculated with heavy Microbes. So what nutes are you using? I will say the Led seems to need more CalMAg so instead of blasting them with higher then typical EC I usually see better results on darker green foliage with steady regimen of foliar and watering with a natural cal/mag I noticed helps alot more.

Like less is more

God damn miracle Gro ….. this is why I hate that shit. Best for ornamental plants IMO.

It has pelletized fertilizer / feeds with EVERY watering / both fast and slow release fertilizer.
So maintaining any feed control is next to impossible. It’s loaded with bark which is very acidic. So ph control is up in the air .
Tried to find “ actual “ buffering elements but none found .

You would be better off with a standard potting mix instead of this “ retail “ mix.
The most glaring part is that it’s recommended for “ in ground “ growth NOT CONTAINERS.

No feed or bottle nute will help while using this soil medium.
