Gluteous, the lucas formula is General Hydroponics (GH) fertilizers for hydroponics. If you use the formula on the bottle, you will be giving the plants too much nitrogen and they will stretch alot. Most hydro growers have limited space and don't want really tall growth, besides the plant will develop a weak stem and need support. You will only need to buy the micro and bloom bottles without the grow. They work really well, they're cheap (relatively) and alot of experienced growers use it. Does that anwser your question?
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
