I have been using miracle grow all purpose, as the base of my hydro solution. How much should be added per gallon, to get the numbers they post? Have been using half of what they say for outdoor plants. Which works out, with other additives, to around 1500 ppm, including about 300 for the tap water.
Seems to do fine, but want to make sure I am on track.
Thanks!!!
