Many people that are new to a hydroponic system have no idea on how to feed their plants, and they get a million different answers from a million different people, then they get even more confused.
The chart below is one that I made myself and its for Fox Farm nutes only.
I learned the hard way that the FF chart given with the nutes is no good for most strains and will burn, kill, most plants specially in their early stages, so I decided to experiment with varius levels of nute strengh, and found that this chart works the best for all the strains that it was tested on, I use tap water because my tap water has a low ppm.
This chart is a very safe chart to go by, no worries on over feeding the plants, wich can cause some serious problems either right away or long term, it has an initial ec that is low, then moderate, then high.
This chart is for a 4 wk vegge period and an 8 wk flowering period, if you were to use this chart, and vegge longer than 4 wk's all you need to to is continue following the chart as it goes into the flowering chart but continue to use the grow big, versus the tiger bloom, that's all, very simple, and dont use the solubles, the solubles are for flowering only.
If you flower for more than 8 wk's all that you need to do is continue following the chart from wk 12.
Has the ec is raised the ph will remain more and more stable, I recomend using distiled water, for the first 2 to 3 wk's of the plants life then tap water can be used IF the ppm is not to high, if the ppm in your tap water is high either cut back on the nute solution on this chart by 1,25ml per galon, or continue to use distiled water or RO water.
I also recomend using 1/2 cup of hydrogen peroxide for every 20 galons of water twice a wk ( every 4 days) I found it helps keep the roots nice and clean.
1 Tsp = 5ml
1 Tbp = 14ml
Lights on 24/0
Starting seed or clone:
Grow Big- 1.25ml galon
Big Bloom- 2.5ml galon
This chart starts once the seedlings are 1 wk old from seed, or clones are 1 wk old.

Glossary:
Phenotype: The phenotype of an individual plant is either its total physical appearance and constitution or a specific manifestation of a trait, such as size, color, or height that varies between individuals. Phenotype is determined to some extent by genotype, or by the identity of the alleles that an individual carries at one or more positions on the chromosomes. Many phenotypes are determined by multiple genes and influenced by environmental factors. Thus, the identity of one or a few known alleles does not always enable prediction of the phenotype.
pH: pH is a measure of the activity of hydrogen ions (H+) in a solution and, therefore, its acidity or alkalinity. Many plants require a certain pH in the substrate in order to absorb nutrients properly. For cannabis the pH in a hydroponic system should be between 5.2-6.3 but the ideal ph is 5.7 to 6.
EC level: Electrical conductivity (EC) is a measure of a material's ability to conduct an electric current. Mineral salts dissolved in solvents influence the electrical current. An EC meter can therefore measure the amount of salts in a nutrient solution.
SOG: Sea of Green; close planting in rows to maximize plants per m2/f2 from seed or clone.
SCROG: Screen of Green; growing the plants through a wire mesh for bushier and even top growth of flowering shoots.
LST: Low stress training as defined by tying plant stems down rather than pruning them.
