This is the lucas formula up to about 1200 PPM's and then additives. Cal-mag, B52 and that's it. 1000 HPS as close as I can get it.
LOC NAR1958 Reviewed by LOC NAR1958 on . Lucas Formula when using LF do you include additives in the 800ppm ceiling, ie. floralicious plus, green fuse bloom, silica, epson salts, chi, koolbloom, etc... OR do you just add them after you have 800ppm with GH bloom and Micro??? Rating: 5
