Thanks for the quick response

I currently have a ph meter that i got off of ebay so i will be able to monitor that at least.

So let me see if I got this right. Your saying with my current setup that i want to basically starve the plant then add the fox farm ensuring that I dont over feed the plant?

Again sorry for being such a noob at this..
