In my humble opinion, you won't even need to use any pH adjusting product with the already pH stable soil mix you are using. Unless your water supply is highly alkaline, let your soil mix do the work. Manually adjusting the pH of your water supply, and especially in an organic gardening paradigm can work adversely in the grand scheme of things. Chunk
