Just started a DWC a couple of days ago. I could not find any "Hydroponic"
nutrients around town. So I got Espoma Plant-Tone. 5-3-3 organic with enhanced microbes. My plants seem to look like they like it. I put in 7 table spoons full for about 15 gal of water. I didn't have a clue on how to mix it. I guess I'll see how it works out. I don't know anything about when I should ad more nutrients. I look forward to leaning from here thank you all in advance.
