tell me I'm wrong, I'm asking

why did the hygrozyme bring the ph down to 5.1 from 5.7? .....was I wrong in bringging the ph back to 5.7?

I don't know why it brought down the pH, but anything from 5.2 to 6.5 I wouldn't really change. People try and hit a target of 5.8 and that's good, but I think it's difficult for a beginner and you end up chasing your pH too much. While you are just starting, the theme of what I have been telling you is less is more and just be mellow with your plants.
