yeah man, there are posts all over the place that talk about PH problems. I also don't grow in soil, but I've read a little about it. As I recall, it seems like people kept their PH's closer to 6.0. I am sure of this: Even growing is soil, a PH of 7.6 is way too high... Check around the site, you'll find your answers. That's the best advice I can give. Other than: Get that PH under control asap. When your ph is out of whack, your plants can not get the nutrients they need...never a good thing.
