why are the leaves turning yellow?

so you can have medium with ph of 14 and no problems?

can you provide a link where i can see this?

also, you should adjust your feed so every watering is feeding
I have been growing in soil for years and never once have I needed to PH anything. One of the benefits of growing in soil is you don't really have to bother with that. We have been growing veg for years and years and never once had to PH anything. In coco or hydro I see the point, but not in soil.

Can you provide a link of a medium with a ph of 14? I've never heard of one. If the soil has a thriving microbiology, no need to ph. The microbes will adjust it to their liking. Same thing happens in nature.
Not at the moment, haven't looked into it.

why do you think so many bag soils put ph buffers/stabalizers in their mixes (usually dolomite lime or similar)? and there are premade soils with different ph's directed towards different plants. i.e. 'acid loving plants', like cannabis.

because ph matters to plants.

I can't even fathom implying that ph doesn't matter in any growing medium, it's beyond me.

that's awesome, what is the ph of your soil?

sodium hydroxide best i can come up with. if you tried to grow in it, that would be your growing medium.

By no means am I saying that the ph doesn't matter to plants, but who ph's the water for plants growing on a prairie? I guess I should've stated living organic soil. Dead soil that you're just using for somewhere for roots to grow, then you'll need to ph.

i don’t know what that means, you said something like your plants do well in your soil, I asked the ph of your soil. Mine is 6.3 and water with 7.0. It seems to be working very well.

do you know the ph of your soil?
I see what you're saying. If your soil is inert, and you're feeding synthetic nutes, then yes ph your input water.

Imo though, if I was going to grow in an inert media, I'd probably go coco. Id have a better growth rate.

The lime or oyster shells or whatever is in his potting mix has ph stabilizers in it..it will keep it in check. No need to ph anything if using soil.

Almost every potting mix has a ph around 6.4 or 6.5.. with a ph stabilizer in it to buffer any swings

I'm organic, tap comes out 7, that’s why I made it 6.3 thinking tap is going to make it rise a bit to 6.5, which is from my research near optimum for soil to grow weed

any buffer I know of has a finite life span, so still, if having issues that seems rootzone related, ph should be the first thing to make sure in range, for any growing medium

aside from obvious under or overwatering

Nope, never tested it. I test my water quite often as I have a hot tub, my water is 6.5 - 6.7.

Hello everyone!

these are about 14 weeks old i noticed that yhe leaves are turning yellow?
ur advise is highly appreciated!View attachment 5030201View attachment 5030201View attachment 5030202View attachment 5030203
That mix looks damn dry and pot kinda small. It might be the culprit since you provide nutrients… all purpose dry salt is just fine but might lacking on magnesium, not sure about the second one and how it affects nutrient balance in your medium. How do they respond on watering? Do you observe some leaf movement up or down when water?

I have never seen those numbers… actually I have seen those numbers on the bag like 6,2 or whatever untill Bluelab said no way dude. They were all 5,5 and less…
