Once you get your Ph meter, make sure to adjust the ph to where you want it slowly. When I got mine and noticed that my water I had been using was at like 7.9 PH, I immediatly adjusted down to 6.0. Just about killed my plants. Step it down slowly to where it should be. Of course, you may want to bounce that off the rest of the community, as I am also doing my first grow right now, and by no means an expert. Keep the pics coming!
