Soil PH
For the Great White Shark grow I used a soil PH of 7. A neutral PH makes for a simpler grow. The next time I grow I will drop the PH to around 6.2 (slightly acidic). Pot plants will absorb nutrients better in acidic soil. Adjusting soil PH is more challenging, so it’s best to try growing without any ph changes, and eventually building up to the more advanced methods.
