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 it.

Thank you,
