Am still curious what soil you're using. 7.5 ph is pretty high for a potting mix. Are you using a cactus mix...or mixing your own...?
Rusty Trichome Reviewed by Rusty Trichome on . Need advice:Trying to adjust SOIL PH level Soil Ph level at 7-7.5 tested.I know that's high for soil. Using 3 gallon pots, Into 3rd week of grow and leaves turning yellow. Which is what told me to check PH.Anyhow added 2 tps. of Sulfur granuals (as per package directions) to each pot, mixing in to soil. Can anyone PLEASE tell me how long it will take to see results.
