OK so used PH up 2 times so far and plant is growing good, I have not killed it with the PH up yet. I am starting to think using PH up kills the microrhizome is a myth. I used 5 drops in around 20 OZ of water 2 times. Plant is in a 6" pot and was not growing at all and now has doubled in size. Going to start feeding with cal mag as it is still purple as hell and will start to introduce nutes soon.
