Teehee! I used one of those when I first started growing! Yeah those things are crap! Kind of fun to play with, but def. not accurate.

You just have to add and test, until you get it to where you want. Get it to about 6.5 and add your nutes.
carinia Reviewed by carinia on . Yellow leaves Currently have three of my daughters in their third week of flowering and I have yellow leaves showing up. Also, have tested the pH of my soil and find it ranging from 7.0 - 8.0, very alkaline. I would like to get my pH back in range, 6.0 - 7.0, but do not know how to go about it? Any help you can provide is appreciated. Below is the Trouble Form I have filled out and I hope that I have provded enough information so that you will see what I have done wrong and what I need to do to correct Rating: 5
