PH questions

Hey, All.

My plants seem to be about 2-3 weeks away from harvest. I have just started my final flushing process, and my PH meter is saying that the soil is about 6.9-7.1

I understand that I am supposed to have the ph down around 6.5-6.9, but I do not want to add anything to reduce ph that will then end up in my final product.

I was wondering if there are any additives that might rectify this problem, and also is this actually a problem considering harvest is just around the corner?

I am growing in my backyard, in Central coast california, and my plants look very healthy. I have maintained a ph of around 6.8-7.0 throughout the entire grow, with seemingly beautiful results. My feeding water is around 6.9-7.1 and has seemed to work very well throughout. I know that my fert mixes grought the 7.0 water down to about 6.8, but not adding any nutes from here til harvest...unless totally necessary.

My strains are: Bubbleberry(Bluberryxbubblegum), Blue dream(blueberryxSuper silver Haze) and GDP(pure indica)

Any advice would be greatly appreciated

how are you measuring the ph of the soil ?? if your growing in soil ,in containers ,in your backyard, and your water is already at 7ph then it does not need adjusting. farmers adjust ph to keep nutes available to the plants but at two weeks from harvest you'll want to LIMIT the food intake by the roots and force the plant to cannibalize it's leaves.a fully ripe, ready to harvest plant will appear to be dying.
