I will say now, I'm somewhat of a beginner. I feel a bit more confident posting this here considering I've recently caught the notion that some people don't really care about PH. So here's the thing... Growing 4 girls outdoors, 1 is in a 25 gal smart pot, and 3 are in the ground. The smart pot has Fox Farm Ocean Forest while the 3 in the ground are just working with the soil that was there. They've been going for about a month now, and they all appear really good to be honest. No signs of deficiencies whatsoever. However, I got a BlueLab Soil PH Pen, calibrated it, and went testing, and all the readings I got were within 5-5.5. So my question is; how do I go about raising the PH? I know I need to do it slowly over time, and I've seen some suggested methods of action, but I need specifics. I need to know what you used, how you used it, and results. How does one go about amending soil? I've also been feeding with GH Flora Series every so often (maybe 2 times thus far, with watering in between as needed) and adjusting the PH of the solution using PH Up and PH Down. Thanks for the help fellas. P.S., the white power is diatomaceous earth, had pleasant results with it.
