Soil PH staying at 7.5-8

Hey All,

First off, thank you for any advice up front. Appreciate you all.

Now.

Strain: Ceres Kush, BlimBurn Mango, BlimBurn Tijuana
Medium: Pure Ocean Forest and a few vegging in an Ocean Forest/Bionix #5 mixture. Bionix is a coco/perlite mixture
Nutes: Fox Farm Trio + Solubles, CalMag+, occasional Bush Doctor MicrobeBrew
Digital PH Pen is a Hannah PHEP4 calibrated once a week

Ok, I PH my nute mixtures and pure H2O feedings to 6.2-6.8 whether it be up or down.

Runoff is usually around 5.5, however, my ph 3-in-1 soil probe is reading the "stable" PH of the soil is 6.5-7 directly after watering, however within a couple hours I am at 7.5-8

I've been growing for just about a year now, so I have a few under my belt. The first strains I grew were from an old friend and they have been established for 15+ years. In the beginning I never read ph of anything. Just mixed up the juice and poured it in my plants. Had a few colas the size of my arm. As soon as I started these new strains shit kind of went down hill. Getting crunchy browning, copper spotted leaves.

Now I understand genetics could be a very serious possibility, but now that I am checking there is obviously something going on in my garden. No matter what I PH my juice to the soil will always creep back up to the 8 range.

Any ideas what could be happening here?

Again, thank you for any advice/tips given.

It could be you have a little bit of a buildup/lockout...
Get some Dolomite powder, regular tap water (dont worry about ph) and flush through.
Should clean out any buildup, buffer the soil, and next feeding just go as per usual and let us know how you go...
A little bit of seaweed also help the roots repair, health and assists nutrient uptake... but is optional

Cheers Jimmy.

I just bought some dolomite, I know I should have been using it from the beginning. I haven't top dressed with it yet, but am mixing it into my soil bin. I have flushed them a few times with pure water over the last several weeks and yesterday ran some FloraKleen through them.

Try pouring gasoline. I think it's 5 oz per gallon and 3 times your container volume while smoking a cigarette

Granulated Dolomite works well, but you need ti mix in from the beginning.
Failing that, Dolomite powder works well. I use a product called Eco Dolomite... very natural and effective.

Be careful with straight pure/distilled/RO water usage. Straight RO and Distilled water should never be used on plants imo.
It contains no elements which causes it to draw out from the plant much alike putting salt on a leech.
RO and distilled should only be used as a base to add nutrients to. It is used to have greater control of the elements available to the plant instead of the variables of town/well water.
If the plants are in pots and you can use 'H&G Drip Clean' to greatly reduce the amount of salt buildup if needed.
With Dolomite in the soil, PH'ing the water is generally not required. PH'ing is for hydroponics. Plants have been grown for thousands of years without PH'ing and grow just fine with correct soil preparation

Cheers Jimmy.

My bad. By "pure" I meant no nutes. I use my tap water which is between 15 and 24 ppm. It's pretty clean.
