Well I think my soil has gotten slightly more acidic than it was when I started 3 weeks ago but it's still not really in the trouble range. I was wanting to stave off any pH problems before they occur. I had a pH problem last time I grew, which was also my first time, but I was using a soil that was largely peat moss.

I'm using what I think is promix now, but I'm still worried that the soild will get too acidic as I feed it. I'm using fox farm grow big, tiger bloom and big bloom as my ferts, by the way.
