Nice... Nice... I am running similar set up like yours. You stated something about this on one of my posts. It looks very good.I myself had to do alot of reading on the e.c. and ppm as it pertains to nutes. Had to do one of those Oh Shit dumps like you are talking about. I added the requested amount but on the well water I'm on it shot to 1600 ppm over night. How I'm not sure.Dumped anyway and went with a one part grow with one additive.I sure hope my flowering period goes as well as yours looks like it is. I'm signed on and will be watching you progress.:thumbsup:
