Soil pH not adjusting even after watering pH water.
Dormandostarted grow question 3y ago
So Far I've been 6.5-7 pH water, & organic ferts BioThrive Grow, Bloom & CalMag. The soil pH doesn't seen to go any below 6.5; even though I've been feeding 5 pH water to make it lower. Why is this happening? What to do? Does organics in the soil auto-adjust the pH all by itself

1st things 1st.
Organic nutrients react differently in a soil set up. My alga grow is 4.5 when putting in.
My Bioenhancer from Green House Feeding puts the ph ai 9.5
My point is. Unless you're adding synthetic nutrients, (which you should try avoid, as the organic process doesn't follow PH rules. With most organic nutrients with soil. ph does not need adjusting.
Good

6.5 - 7.0 in soil is perfectly fine. Adding acidic water (5.0) to soil will not change the pH of the soil. To lower the pH of the soil, top dressing with agricultural sulfur will lower soil pH...........but if your soil is anywhere between 6.2 and 7.2, I really wouldn't worry or try and change anything.

That meter shows how fat is milk, but not ph of soil .
Dont try to correct soil. Have wet/dry cycles and load always right ph. For soil its 6.2-6.5 range. I found constant 6.3 works best.

6.5 is fine for soil. 6.8, too. even 7 probably won't cause issues with a good feeding regimen, but there's some benefit to slightly acidic on growth. "auto adjust" is a bit of a misnomer... the bacteria will mitigate some ph swings.. but tehy will also force a resulting equilibrium.. like what you see.. this is the "auto-adjusting" occuring.

"dunking" fabric pots in solution for feeding?I have recently been presented with the concept of "dipping": submerging fabric pot in solution for about 8 seconds and then picking up to drain. It is intriguing to me but I am curious about it causing overwatering or root rot. Thoughts?3y ago

PH measuring for Organic GrowersIf I’m growing organically, do I measure my PH still? I heard that the PH up & down liquid isn’t organic & that organic growers should throw away there PH meter because the soil will adjust to what ever PH level I water them with. Is this true? I’m having a cal/mag deficiency.

Will excessively aerating and circulation change the PH?I have a reservoir which holds my nutrients until they need to be used.

Time to start 2 week flush?Hi 420 Fam. So I would just like to get your opinion on my 3 White Widows. Only SOME brown/slight yellow orange pistils here and there. Tomorrow (26Aug) is start of week 8. Should I start flushing tomorrow to have full 2 weeks, or do these look like I can start flush from week 9?
