I am using some gardeners pride from walmart with a 1/3 perlite mix the third picture is 1/3 gardeners pride 1/3 vermiculite and 1/3 perlite. the third one also was top dressed with some EWC so I'm pretty sure that is why it looks that way I am probably wrong
. Either way there really has been no nutrients added. Some also have happy frog on the top but not much maybe 2 cups. The Ph was high for a bit reading over 8.5+ with a color change test tube. I have thrown some ph down in the water. The run off after that is now at about 6.0-6.5.
