The Tricarboxylic acid is basically just citric acid. Anyways, I think my girl was just a little hungry. Gave her a really good tea mixture I got from Supreme Growers and she bounced right back. I'm a little amazed about how quickly she perked up. A little tidbit I found out about the other day that I'm none to impressed with, speaking with Rick he let it slip that the Cornacopia Plus nutes have an anti-microbial component in them. When I first started using the line of nutes Rick told me they work amazing in conjunction with organics. I'm a little pissed. Anti-microbial and organics definitely don't work in conjunction with each other. I think maybe this is something they should be telling customers before they use those nutes and kill off the beneficial bacteria in their rhizosphere. Anyway, the little lady is back on track and with a little luck and some diligent work she'll stay that way.
