lucas formula doesn't use the grow GH. Just the micro 5 ml and 10 ml bloom to one gallon of water for veg. If you look at the micro- there's plenty of nitrogen in it already. For flower it's 8 ml micro and 16 ml bloom.
Gen Reviewed by Gen 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
