Im not really worried about the amount to use at the moment I wanted advice on the the amount of weeks per growth stage. With the lucas formula is meant for a 100 gallon tank so I've heard.
The Lucas
method was based upon the use of GH bloom that is sold as a x50 concentration and GH micro sold at a x50 concentration. The manfacturer intended it to be used to make 100 gallons of total nutrients mixed at a 1 to 1 ratio.
With the Lucas
method you would use two gallons of bloom and one gallon of micro to make 150 gallons of nutrients. I do not know what concentration they are selling Flrora Nova formulas at presently, but I heard it is more dilute than the two part formulations.
As for weeks at each stage it varies with strains. Ingeneral you use no fertilizer initially. After roots develop it is typical to use dilute nutrients for tow weeks. Veg staes depend on whter you choose to grow a few large palnts or many small plants. Large plants are often veggedfor two to 6 weeks.
Budding times can run from 6 to 10 weeks give or take. If you bought seeds go to the site you bought them from and lok at what they say about the palnts. Indoors versus out doors, bushy or not, indica/afgahni versus sativa, They usually geive a estimation of height and budding duration. Until experience is gained you can usually expect your plants to be taller, less bushy and take 10 to 20 percent longer to bud than stated in the adds.
Wow, when is the Lucas formula bit ever going to die. It is a Lucas method using GH formulas. Lucas formulated nothing. His method uses existing formulations, he created no formulations. Not that I care for the GH people but the formulations used are theirs not Lucas'.
