m0useanswered grow question 4 months ago Soils tend to manage their PH quite well and I would not worry to much about it if the plants are looking good. If it goes above 7.4 that's when I would worry a bit and use more PH down.
With soil grows as well its better to mix in some sulpher to lower its PH or lime to raise it. I find using PH liquids in the water just not as affective.
