Outdoor soil pH spike
GracelessGardensstarted grow question 14d ago
My auto flower outside for some reason, the soil is reading at between 4&5 pH! It usually only gets rain water, if I mix nutes/water I pH it to around 6-6.3 range. The 2 photo's are in the same type of soil, and have had the same additives but pH is 6. Abouta week left b4 harvest

I never ph in soil if you have the microbes to do the job then it's fine. Looks like a lot of nitrogen is present. Selective the plant may be but over run with N will shut the bud production down.give the plant the best life what it wants when it wants.and then the rest of the stuff to make things pleasant. Seaweed of some kind for stress. Hormones and all that good stuff. Keep the soil conditioned with potassium humane or LABS

outdoor doing outdoor stuff...soil doing soil stuff...
pH matters very little in soil. soil is never consistent throughout. you have pockets of lockout, pockets of high protozoa activity, pockets of low pH, and on and on and on and on. this is why you can do so many things wrong in soil and still pull crop.

With only a week left before harvest, whatever causes it - you can not fix it and have the time to see the results. The plant looks fine - ignore that issue for this harvest.
There might be chemical/biological reasons, it might have been an animal peeing in the pot, something might have gone wrong with your mixture, something going wrong with measurement...

Applying some garden lime will raise pH.
Does it happen each time it rains? Probably acid rain. Also, plants selectively grab nutrients over time so that can shift pH too. Byproducts of microbs etc etc.. life is messy.

The plant looks ok regardless of the ph readings. Are you sure you are getting accurate readings? PH pens are notorious for losing calibration and giving false readings. Also, you appear to be growing in organic soil with organic nutrients, PH shouldn’t matter as much in your situation. I also grow with organic soil and nutrients, but haven’t checked or adjusted ph in years. Good luck 👍

Good afternoon,
To start, I think there's more than a week left until harvest... I analyze the pistils and they are still very white, I should use a magnifying glass to be sure... the pH could result from a buildup of nutrients over time... do some flushes to see if it corrects the situation...
