Need soil ph help

I’m using soil/perlite mix. My wwa are about 45-50 days old. My tap water pH is high, like high 8 or 9. After add nutes it’s about​ 6.5. My problem is my run off is super low. I mean like in the 4 area. Plants seem to be fine but still want to fix the ph

Dolomite lime this can be added to your soil to raise ph

Dolomite Lyme is a good organic way to raise your
PH and is available at most garden shops. Or you could get PH up and PH down and adjust your water to bring up the PH. I myself would go with the Lyme.

But I’ve also watered plants with just plain water, which by it’s self is high 8-9. Shouldn’t that alone bring it up

It would depend on the amount of soil and the amount of water I would think it would help bring it up though.
Some people that have PH problems will actually flush there plant with a bunch of water until the runoff becomes stable at the desired PH level.

What type of soil are you using? (I E fox farm ocean forest etc.)

It’s mg. But I’ve already grown one plant in it, recycled the dirt. Really it’s reused soil, a little coir I had left and perlite in 5 gallon buckets

You know anyone who’s grown California dream from ilgm. Just started one and was wondering what to expect

I’ve never reused soil myself so I’m not sure what to expect doing that. Maybe another member can give some insite into that. @Donaldj and @Majiktoker and @bob31 are pretty knowledgeable when it comes to growing.

Reusing soil you can expect a lack of silicate or silicon contained in the soil. When a plant grows an entire cycle in soil it will tend to use up the available potassium silicate or silicon in the soil. With that being said it will uptake other elements at a slower rate, as potassium helps open the availability in element and nutrient uptake

So if reusing get her some sort of supply of potassium silicate to replenish the soil.

Just ran 4gal of 8-9 ph water through and it’s still testing high 4s low 5

Id hold off on giving nutrients for a minute then, slight possibility its a tad bit toxic from last grow

add lime your soil is the way it is because it has a buildup in it from previous use adding lime buffers soil ph long term since most after adding nutrients tend to have low ph

So, just dump some lime on top of soil? Cause no frickin way I can mix it. Roots too thick together. Almost 2 month old wwa in 5 gallon bucket

Yeah you would put it on top of your soil and water it in. I would take like a plastic fork and loosen the top layer of soil then add the lime and kind of work it into the soil then water.
